This quiz titled '5\/22\/19 Population Studies & Interactions Among Living Things Practice' assesses understanding of ecological relationships, including predator-prey dynamics, niches, and limiting factors in ecosystems. It is designed to prepare for the ProProf End of Units Test, focusing on key ecological concepts.

Rate this question:
The population sample equals the number marked multiplied by the sum of the unmarked and recaptured divided by the number recaptured
The population sample equals the number marked minus the sum of the unmarked and recaptured divided by the number recaptured.
The population sample equals the number marked divided by the number recaptured
The population sample equals the number unmarked plus the recaptured divided by the number recaptured

Rate this question:
There are usually few organisms at the top because there is a limited amount of energy available at that level of a food web.
There are usually few organisms at the top because the organisms at the top of the food chain care for their young longer than organisms lower on the food chain.
There are usually few organisms at the top because the organisms at the top of the food chain consume are omnivores that consume diverse kinds of organisms that are lower on the food chain.
There are usually few organisms at the top because the organisms at the top of the food chain are scavengers consuming what other organisms have left behind.
