2) which term best describes energy transfer between trophic levels?

a- average

b- efficient

c- inefficient

d- high

3) where would a primary producer be located in the food chain?

a- first step

b- middle step

c- last step

d- each step

2) The correct answer would be C- inefficient.

The term inefficient would be the best to describe the energy transfer between trophic levels. It is because most of the energy gets lost at a particular trophic level in the form of heat. The organism uses most of the energy available at particular trophic level for its cellular functions.

Only around 10% of the energy is transferred to the next trophic level.

3) The correct answer would be A- first step.

In any ecosystem, the producers occupy the first place as they manufacture or synthesize food from carbon dioxide and water with the help of sunlight.

Consumers (herbivores and carnivores) depend directly or indirectly on the producers to get their nutrition.

The simple food chain can be summarized as:

Producers→ Primary consumers (herbivores) → secondary consumers (carnivores) → tertiary consumers (top carnivores)

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
