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

  1. Deep sea

  2. Freshly formed water pond

  3. Forest ecosystem

  4. All of the above

Show answer
Correct Option: A
Explanation:

(A) In deep sea ecosystem has all structural components,

(B) Freshly formed water pond lacks many abiotic components or structural components like atmospheric condition and water resources are absent.
(C) In Forest ecosystem all structural components are present
Thus, the correct answer is 'Freshly formed water pond.'

  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.
