Snow Sunlight Mice Soil 3 / 15 What will happen to the populations of animals in this forest after the fire? increase then decrease stay the same increase decrease 4 / 15 Why do populations never reach their biotic potential? because there are always limiting factors because there is always plenty of food in a population because there are always many animals in an ecosystem because there are always resources available 5 / 15 When do animals compete for food? When there is plenty of food When there is not enough food When there are very few animals When there are old animals 6 / 15 Define "carrying capacity" maximum number of individuals of a species that an environment can support 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 7 / 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. Competition Reproductive Potential Interdependent Carrying Capacity 8 / 15 When does overpopulation happen? When the population gets larger than the biotic potential 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 9 / 15 What are all individuals of the same species living in the same place at the same time called? population ecosystem community biosphere 10 / 15 Why do animals compete for food? to win a medal to mate to attract another animal to survive 11 / 15 How can overpopulation impact other populations of animals? Less Living Space Available All the Above Less food Available Less Water Available 12 / 15 An ecosystem is 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. a group of populations of living things and the non-living parts of their environment. any area that located on land. 13 / 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 stay exactly the same. The growth of both populations is likely to be limited. Both populations will likely immediately leave the area. Both populations are likely to grow. 14 / 15 A population is a group of 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. a small group of living things that use the same resources. nonliving things that are located in the same area and provide resource for living things. 15 / 15 Define "limiting factor" minimum number of individuals of a species that an environment can support maximum number of individuals of a species that an environment can support when population increases slowly at first then grow at an accelerated rate anything that constrains a population's size and slows or stops it from growing Your score is 0% Restart quiz Go to the Quizzes Page
