When there are old animals When there are very few animals When there is plenty of food When there is not enough food 2 / 15 Define "carrying capacity" when population increases slowly at first then grow at an accelerated rate minimum number of individuals of a species that an environment can support any factors in an environment that are limited maximum number of individuals of a species that an environment can support 3 / 15 What is likely to happen to the populations of zebras and gazelles when they are competing for the same grassy area? The growth of both populations is likely to be limited. Both populations are likely to grow. Both populations are likely to stay exactly the same. Both populations will likely immediately leave the area. 4 / 15 Why do populations never reach their biotic potential? because there are always many animals in an ecosystem because there are always limiting factors because there is always plenty of food in a population because there are always resources available 5 / 15 A population is a group of living and nonliving things that are exist in the same environment. living things of the same species that live and reproduce in the same area. nonliving things that are located in the same area and provide resource for living things. a small group of living things that use the same resources. 6 / 15 An ecosystem is a group of populations of living things and the food sources in their environment. a group of populations of living things but NOT the non-living parts of their environment. a group of populations of living things and the non-living parts of their environment. any area that located on land. 7 / 15 What will happen to the populations of animals in this forest after the fire? stay the same decrease increase increase then decrease 8 / 15 The struggle between two or more species or individuals in an ecosystem that require the same resources, such as food, water, sun, or territory. Interdependent Competition Reproductive Potential Carrying Capacity 9 / 15 What are all individuals of the same species living in the same place at the same time called? ecosystem community biosphere population 10 / 15 Which of the following is an example of a limiting factor for an owl? Sunlight Mice Snow Soil 11 / 15 Why do animals compete for food? to win a medal to attract another animal to mate to survive 12 / 15 When does overpopulation happen? When the population gets smaller than the biotic potential When the population gets larger than the biotic potential When a population gets smaller than the carrying capacity When a population gets larger than the carrying capacity 13 / 15 How can overpopulation impact other populations of animals? Less Water Available All the Above Less Living Space Available Less food Available 14 / 15 Why don't populations grow indefinitely? only abiotic factors only biotic factors none of the above limiting factors 15 / 15 Define "limiting factor" maximum number of individuals of a species that an environment can support minimum number of individuals of a species that an environment can support anything that constrains a population's size and slows or stops it from growing when population increases slowly at first then grow at an accelerated rate Your score is 0% Restart quiz Go to the Quizzes Page
