In a freshwater ecosystem, secondary consumers capture approximately 10% of the energy that primary producers (like plants and phytoplankton) capture from the sun. This follows the general rule of energy transfer in ecological systems, known as the 10% Rule, where about 10% of the energy is transferred from one trophic level to the next. Thus, the correct response is 10%.

Which of the following best describes the energy flow from producers to tertiary consumers in a freshwater ecosystem?(1 point)
Responses

Energy flows directly from the sun to tertiary consumers.
Energy flows directly from the sun to tertiary consumers.

Producers get 100% energy from the sun, primary consumers get 10%, secondary consumers get 1%, and tertiary consumers get 0.1%.
Producers get 100% energy from the sun, primary consumers get 10%, secondary consumers get 1%, and tertiary consumers get 0.1%.

Tertiary consumers get the most energy directly from he sun.
Tertiary consumers get the most energy directly from the sun.

Energy is evenly distributed among all trophic levels.

The best description of the energy flow from producers to tertiary consumers in a freshwater ecosystem is:

Producers get 100% energy from the sun, primary consumers get 10%, secondary consumers get 1%, and tertiary consumers get 0.1%.

This option accurately represents the decreasing amount of energy that is transferred from one trophic level to the next in an ecosystem.

If the population of freshwater snails decreases significantly, what is the most likely impact on the secondary consumers in the ecosystem?(1 point)
Responses

The secondary consumers will increase in number.
The secondary consumers will increase in number.

The secondary consumers will have less food available and may decrease in number.
The secondary consumers will have less food available and may decrease in number.

The secondary consumers will switch to becoming primary consumers.
The secondary consumers will switch to becoming primary consumers.

The secondary consumers will receive more energy from the sun.

The most likely impact on the secondary consumers in the ecosystem if the population of freshwater snails decreases significantly is:

The secondary consumers will have less food available and may decrease in number.

This is because secondary consumers rely on primary consumers (like freshwater snails) for food. A decrease in the snail population would result in reduced food availability for secondary consumers, potentially leading to a decline in their numbers.

Which of the following organisms is classified as a decomposer?(1 point)
Responses

Water lilies
Water lilies

Earthworms
Earthworms

Freshwater Turtles

Dragonflies

The organism classified as a decomposer from the given options is:

Earthworms.

Earthworms play an important role in breaking down organic matter and recycling nutrients back into the ecosystem, thereby contributing to the decomposition process.
