A scavenger is an organism that feeds on dead animals. They play an important role in the ecosystem by helping to clean up and recycle nutrients from dead organisms. Scavengers typically have adaptations that allow them to locate and consume carrion, such as a keen sense of smell or specialized feeding structures. Unlike carnivores, which actively hunt and kill their prey, scavengers primarily rely on finding already dead animals for their food source.
4.
Consists of many overlapping food chains.
Correct Answer
C. Food Web
Explanation
A food web consists of many overlapping food chains. It represents the interconnectedness of different organisms in an ecosystem and shows the flow of energy and nutrients through various feeding relationships. Unlike a food chain, which only shows a linear sequence of organisms, a food web includes multiple chains that are interconnected. This allows for a more accurate representation of the complex interactions and dependencies within an ecosystem.
5.
An ________ _________ shows the amount of energy that moves from one feeding level to another in a food web.
Correct Answer
D. Energy pyramid
Explanation
An energy pyramid shows the amount of energy that moves from one feeding level to another in a food web. It represents the flow of energy through different trophic levels, with energy decreasing as it moves up the pyramid. The base of the pyramid represents the primary producers, such as plants, which have the highest energy content. As energy is transferred to higher trophic levels, such as herbivores and then carnivores, the amount of energy available decreases. The energy pyramid helps to illustrate the importance of primary producers in sustaining the energy flow in an ecosystem.
