What is the original source of energy in a food web?
-
Decomposers
-
Consumers
-
Producers
-
The Sun
Correct Answer
A. The SunExplanation
The original source of energy in a food web is the Sun. The Sun provides light energy, which is converted into chemical energy through photosynthesis by producers (such as plants) in the food web. This energy is then transferred to consumers (such as animals) when they consume the producers. Decomposers break down the remains of dead organisms and release the stored energy back into the ecosystem, but the ultimate source of this energy is still the Sun.Rate this question:

What is the role of a consumer in the flow of energy through a food chain?
-
Obtaining necessary nutrients from the soil
-
Transforming the Sun's energy to make food
-
Gaining energy by eating other living things
-
Decomposing the remains of living things
Correct Answer
A. Gaining energy by eating other living thingsExplanation
Consumers play a crucial role in the flow of energy through a food chain by gaining energy through the consumption of other living things. They obtain energy by feeding on producers (plants) or other consumers (animals), thereby transferring the energy stored in the food to themselves. This energy is then utilized by consumers for various life processes such as growth, reproduction, and movement. By consuming other organisms, consumers help to transfer energy from one trophic level to another, ensuring the flow of energy through the food chain.Rate this question:

A diagram of a prairie food web is provided. Which organism in this food chain gets its energy, indirectly, from prairie grass?
-
Squirrel
-
Mountain lion
-
Robin
-
Eagle
Correct Answer
A. Mountain lionExplanation
The mountain lion gets its energy indirectly from prairie grass because it preys on animals, such as the squirrel, that directly consume the grass. The squirrel, in turn, relies on the grass as a source of energy. This creates a chain of energy transfer from the grass to the squirrel, and then to the mountain lion.Rate this question:

A diagram is provided. The food web depicted here would be able to support the smallest number of which of the following organisms?
-
Diatoms
-
Shrimp
-
Squid
-
Tuna
Correct Answer
A. TunaExplanation
The food web depicted in the diagram shows a hierarchical relationship between different organisms. Tuna is a large predator that feeds on smaller organisms like squid and shrimp. Diatoms, on the other hand, are microscopic organisms that form the base of the food chain by producing food through photosynthesis. Since diatoms are at the bottom of the food chain, they can support a larger number of organisms, including shrimp, squid, and eventually tuna. Therefore, tuna would require the smallest number of organisms to be supported in this food web.Rate this question:
