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