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