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

Which of the following ecosystem lacks one or more structural components?

  1. Deep sea

  2. Freshly formed water pond

  3. Forest ecosystem

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
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.'

C Correct answer
Explanation
A drop of water is an example of nano ecosystem. Nano-ecosystems are smaller ecosystems that are specially contained within larger ecosystems but have individual characteristics. It is part of mega ecosystem. 
So, the correct option is 'macro ecosystem'.

Ecosystems may be defined as

  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
Reveal answer Fill a bubble to check yourself
D Correct answer
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.
