Answer 1

Answer:

which of the following requires maximum energy

1) secondary consumer

2) primary consumer

3) primary producer

Answer : Primary producer

Answer 2

Answer:

Option 3) primary producer

Explanation:

• The primary producers are the autotrophs i.e. can synthesize their food. They provide food, shelter, and O₂ to the consumers. They are called transducers because they change light energy to chemical energy.

• For example, In terrestrial ecosystems, producers are the green plants, phototrophic bacteria, algae etc.

• While in aquatic ecosystems, it is the phytoplankton (floating plants) and in shallow water, it is macrophytes (rooted plants) that play the crucial role of producers.

• They require maximum energy at this trophic level as the subsequent organisms in other trophic levels depend directly or indirectly upon producers for food and energy.

Hence option 3) primary producer requires maximum energy is correct.
