7 0

Answer:

Explanation:

Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled.

An ecologist is studying the effects that a population of predators is having on a population of prey. He used data from the fie
Anna11 [10]

The correct answer is - D. The population of prey decreases with an increase in the population of predators.

The predators have a very important ecological role, to regulate the number of the prey animals, or rather of the herbivores. The predators are carnivores, which means they eat meat to survive, thus kill other animals to get food. By having an increased number of predators, the population of the prey animals decreases. The reason for that is that the predators need to kill the prey animals, and as their numbers grow, they will kill more and more animals of prey. That will lead to a decrease in the population of the prey animals, but also make a balance in the environment between the plants, the prey animals, and the predators, a balance that will enable all of them to exist and function properly.
