TEAM GRADE 7 COMPETEN CY (#11) STEM TEST ITEM ACCEPTAB LE ANSWER Predict the effect of changes in one population on other populations in the ecosystem (S7LT-IIi-11) Population is a group of individuals of the same species living and interbreeding within a given area. A change to a number of one population could have a domino effect on other populations. Suppose there is a sudden decline in the population of a top predator, such as a wolf, in a forest ecosystem. Without the presence of wolves to keep their numbers in check, the population of herbivores like deer may increase rapidly. This surge in herbivores can overgraze the vegetation, leading to a scarcity of food for other herbivores such as rabbits. Consequently, the rabbit population may decline, affecting animals that rely on them as a food source, such as foxes and birds of prey. What is a population? B A) A group of individuals of the same species. B) A group of individuals of the same species living and interbreeding within a given area.

(2-3 sentences will do) (Answer may differ) This is an extended abstract since students will give a generalization out of the passage given. The decline in the rabbit population, caused by the scarcity of food, has implications for animals that rely on rabbits as a food source, such as foxes and birds of prey. With fewer rabbits available, the predator populations may also experience a decrease in their numbers.
