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