This set of Energy Management Objective Questions & Answers focuses on “Food Webs”.


1. Why is a food web more realistic way of portraying an ecosystem than a food chain?

a) Because it shows the relation of organisms with each other in a habitat

b) Because food chains use only a small sampling of organisms

c) Because it doesn’t shows the relation of organisms with each other in a habitat

d) Because it compares the number of consumers to the number of micro-organisms.

Answer: a

Explanation: Food web is more realistic due to the fact that we can add more organisms into the mix and show how they interact with each other in an ecosystem. In food chain we are just doing a small segment of about three or four animals in a basic food chain.

2. What is called for an organism that helps to define an entire ecosystem?

a) Super species

b) Keystone species

c) Dominant species

d) Precious species

Answer: b

Explanation: Keystone species have low functional redundancy. Any organisms from plants to fungi can be a keystone species. They are not always most abundant species in an ecosystem. The way animals influence food webs varies from habitat to habitat.

3. What is called for the diagram that shows how food chain linked together into more complex feeding relationship?

a) Food web

b) Food chain

c) Food circle

d) Food triangle

Answer: a

Explanation: A food web consists of all the food chains in a single ecosystem. All the interconnected and overlapping food chains in an ecosystem make up a food web. Unlike a food chain, organisms in food web occupy more than one trophic level.

4. Which of the following condition is true for food web?

a) A food web only follows just one path

b) A food web ends with a producer

c) A food web starts with a consumer

d) A food web shoes many paths plants and animals connected.

8. Why are the trophic levels is in the shape of pyramid?

a) Due to loss of energy between the trophic level

b) Due to good looking

c) Due to increase of energy between the trophic level

d) Due to stable energy between the trophic level

Answer: a

Explanation: The pyramid shape of the trophic level comes from the loss of energy between the levels. The chain grows only 10% of the energy supply to the proceeding animals, that energy loss will be used to produce new primary consumers.

9. Which pyramid is always upright apart from tree ecosystem?

a) Pyramid of Number

b) Pyramid of Biomass

c) Pyramid of Energy

d) Pyramid of Force

Answer: a

Explanation: Pyramid of a number represents the total number of organisms at each trophic level. It is always upright except in a tree ecosystem. In tree ecosystem pyramid of number is inverted. Usually, it contains four trophic levels.
