Ecosystem may be defined as 

evs - i issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

  1. A localized association of several plants and animals

  2. Different communities of plants, animals and microbes together with thier physico-chemical environment

  3. Different communities of plants microbes plus their physico-chemical environment

  4. None of the above

Show answer
Correct Option: B
Explanation:

An ecosystem is a natural system consisting of all plants, animals and microorganisms (biotic factors) in an area functioning together with all the non-living physical (abiotic) factors of the environment. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. Ecosystems are defined by the network of interactions among organisms, and between organisms and their environment.

The two components of an ecosystem are 

evs - i issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

  1. Biotic and abiotic

  2. Plants and animals

  3. Weeds and micro-organism

  4. Plants and light

Show answer
Correct Option: A
Explanation:

Two main components exist in an ecosystem: abiotic and biotic. The abiotic components of any ecosystem are the properties of the environment; the biotic components are the life forms, that occupy a given ecosystem. 

Examples of abiotic components are temperature, average humidity, topography and natural disturbances. 
Examples of biotic components are producers, such as plants and consumers, such as humans. 

Ecosystems may be defined as

commercial applications issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

  1. A species along with environment

  2. Plant found in water

  3. Plants found on land

  4. All plants and animal species along with environment

Show answer
Correct Option: D
Explanation:

An ecosystem includes all the living organisms and all the nonliving components of their environment. It comprises of all living things namely plants, animals and organisms interacting with each other and also with their non-living environments, that is earth, air, water, sun, soil, climate, atmosphere, etc. 

Each ecosystem is unique and has three basic components that are autotrophs, heterotrophs and non-living matter. Most autotrophs in an ecosystem are plants while most of the heterotrophs are animals. 
Thus, the correct answer is option D.
