Question

List and describe at least two ways energy is used at a trophic level, thus decreasing the amount of energy available to the higher trophic levels.

a) Energy is used for growth and reproduction, reducing the energy available for consumers.
b) Energy is used for maintaining body temperature, decreasing the energy available for predators.
c) Energy is used for locomotion and finding food, limiting the energy transfer to higher trophic levels.
d) Energy is used for cellular respiration, leaving less energy for consumption by higher trophic levels.

Answer 1

Energy is used for growth and reproduction, reducing the energy available for consumers. Energy is used for maintaining body temperature, decreasing the energy available for predators.

Step-by-step explanation:

Two ways energy is used at a trophic level, decreasing the amount of energy available to higher trophic levels, are:

1. Energy is used for growth and reproduction, reducing the energy available for consumers.
2. Energy is used for maintaining body temperature, decreasing the energy available for predators.
