Hello guys let's cover our homework
1 plastic pollution= plastic pollution is the accumulation of plastic objects and particles example plastic bottle plastic bag in the earth's environment that adversely affect human wildlife and their habitat
2= ecology= Ecology is the study of organisms and how they interact with the environment around them
3= ecotone= ecotone is the zone where two communities meet and integrate example grasslands between forests and desserts another example freshwater and saltwater
3= energy flow= the flow of energy through living organism within an ecosystem is called energy flow example one trophic Level to another trophic level producer consumer and decomposer
4= what is flora and what is fauna and flora is a plant life and fauna is animals
5= trophic level= the various steps in a food chain or ecological pyramid at which the transfer of food or energy takes place from one organism to another organism is called trophic level
6=food chain= the flow of nutrients and energy from one organism to another organism at different trophic levels forms a food chain example of non living organism eats another organism and later that organism is consumed by another organism
7=food web= a network of different food chain is called food web
8= biomagnification= increase in concentration of pollutant in food chain is called a biomagnification
9= bioaccumulation= increase in concentration of pollutant in an organism is called bioaccumulation
10= biotic interaction= biotic interaction refers to the relationship among organisms is called biotic interaction
11= ecological succession= ecological succession is the process by which the mix of species and habits in an area changes over time gradually these communities replace one another until a climax community or until a disturbance like fire occurs
12= nutrient cycle= they are exchanges storage and transfer of biogenetic nutrients through various components of an ecosystem so that the nutrient can be used again and again is called a nutrient cycle
Guys pardon me if I did any mistake during writing this comment❤

Maim aap bahut accha teaching kara rhi hai aur aapke wajah se mere sare concept clear ho ja rhe hai. ( Political science, Geography )

Eco-system first time word used by A.G tansley and (ecology) first time word used by Ernst heckel in 1886 49:27

[muskanjain]

Ecosystem is relationship b/w organisms and environment in which all plants, animals and humans are dependent and interdependent on each other.

Environment is a word derived from a french word "environer' which means neighbourhood. It is a basic life support system. The place, people, things, nature, all that surrounds any living organisms is called Environment.
Two major components of environment are Biotic and Abiotic.
Biotic components are those that include living organisms. Its types with example are:
Producer: green plants; Consumer: primary, secondary, tertiary; Decomposer: bacteria, fungi
Abiotic components are those that include non-living organisms like land. These can be differentiated on basis of climate(rain, temperature, light) and soil/edaphic(topography, minerals)

Four examples of human made environment are roads, buildings, bridges, monuments

Lithosphere(Lithos means stone/rock is the solid portion of the earth. The rigid outer most part of the earth which consists of crust and upper mantle.

Biosphere is the combination of all spheres- there exists lands, air, water i.e life supporting conditions, has presence of living organisms.

Environment:- it's a French word "environed" which means neighbourhood, means to surround and enclose.The place, people, think, nature that sorround any living things or organism is called environment.
Components:- it is two types biotic and abiotic
Biotic Component:- Here includes the world of living organisms. Ex:- plant's and animal.
Abiotic:- The world non living Organisms.
Biosphere:- The part of the earth surface and atmosphere in which plants and animals lives .
Habitat:- The place or environment where a place or animal naturally or normally lives and growth.
Biome:- A biome is an area classified according to the specific that lives in that location.e.g. forest or tundra.
Ecology:- The relationship between living things and their sorrounding.
The principal of organisation:- There are five levels of organisation, and all levels are listed according to their size in increasing order - from small to large
Organisms- population - community - ecosystem - Biosphere.
Principal of ecology:- It's state that production is to be based on ecological processes, and recycling. Nourishment and well being are achieved through the ecology of the specific production environment.
Ecotone:- an ecotone is an are that acts as a boundary or a transaction between two ecosystem. A common example could be an area of marshland between a river and it's river bank.
Ecological niche:- in ecology, the term "niche " describes the role an organisms plays in a community. A species niche encompasses both the physical and environmental conditions it requires, and the interaction with other species.
Energy Flow:- energy flow is the flow of energy through living things within an ecosystem.
Tropic Level:- the tropic Level of an organisms is the position it occupies in a food web.
Food chain:- a series of organising which each creature eat the one below it in the series and becomes a sources of food for the organisms above it.
Food web:- a system of food chain that are related to and dependent on each other.

[ The importance of perfect balance between natural and human environment ]:-

Natural environment and human environment are interdependent and have a profound impact on each other. Therefore, maintaining a perfect balance between them is crucial for the survival of both. Let's explore this concept further.

Natural environment

The natural environment consists of all living and non-living things that exist naturally on Earth. It includes ecosystems, plants, animals, natural resources, and climate. The natural environment provides the necessary resources and services that support all life on Earth.

Human environment

The human environment comprises all the human-made structures, systems, and activities that humans engage in. It includes cities, transportation systems, industries, agriculture, and other human activities that impact the natural environment.

The need for a perfect balance

The natural environment and human environment are interdependent, and any change in one can have a profound effect on the other. Therefore, maintaining a perfect balance between them is crucial for the survival of both. Here are some reasons why:

- Natural resources: The natural environment provides humans with resources such as food, water, and air. Humans, in turn, use these resources to sustain themselves and their activities. If the natural environment is damaged or depleted, it can lead to a shortage of resources for humans, affecting their survival.
- Ecosystem services: The natural environment provides crucial services such as pollination, water purification, and climate regulation. These services are essential for human well-being and are necessary for the proper functioning of the human environment.
- Climate change: Human activities such as burning fossil fuels and deforestation have led to climate change, which is having a profound effect on the natural environment. Climate change is causing extreme weather events, sea-level rise, and loss of biodiversity, among other impacts. These effects can also have a significant impact on the human environment, affecting food production, water availability, and human health.
- Biodiversity: Biodiversity is crucial for the survival of both the natural and human environment. It provides ecosystem services, supports food production, and contributes to human well-being. Loss of biodiversity can have a significant impact on both environments, leading to a decline in ecosystem services and food production.

Conclusion

Maintaining a perfect balance between the natural and human environments is crucial for the survival of both. Humans must take steps to ensure that their activities do not harm the natural environment and that the natural environment continues to provide the necessary resources and services that support human well-being. In short, a perfect balance is necessary to achieve sustainable development.
