The size of a population of marine iguanas on an island far from the mainland stays roughly the same. Which of the following must be true? Group of answer choices Birth Rates are equal to death rates Death rates are greater than birth rates Birth rates are greater than death rates None of the above

Birth Rates are equal to death rates

Explanation:

Population, in biological terms, refers to the organisms of the same species interacting together in a given area. In this case, the population consists of marine iguana species living on an island far from the mainland. The population size is the total number of marine iguanas existing in the island.

However, birth rate and death rate can affect the population size of the marine iguana species. The birth rate and death rate refers to the number of births and deaths occuring in the population respectively. Hence, since the size of marine iguana population stays roughly the same, it means that the BIRTH RATES ARE EQUAL TO THE DEATH RATES.
