## Step1<br />A territory is an area that an animal or a group of animals claims as its own and protects from others. This is a fundamental concept in ecology, where animals establish territories to ensure access to resources and to avoid conflicts with other animals.<br /><br />## Step2<br />An example of a parasite is a tick. Ticks are small arachnids that feed on the blood of their hosts, which can be mammals, birds, or reptiles.<br /><br />## Step3<br />Bacteria in your intestines are an example of mutualism if they help your break down food. This is because they aid in digestion and also produce certain vitamins that are beneficial to the host.<br /><br />## Step4<br />Predators kill their prey. This is a fundamental aspect of the predator-prey relationship in ecology.<br /><br />## Step5<br />The property of a population that may be described as even, clumped, or random is the dispersion pattern. This refers to the way individuals are spread out in a given area.<br /><br />## Step6<br />The "co" in evolution means "change". This is derived from the Latin word "mutare", which means "to change".<br /><br />## Step7<br />If a population has plenty of food and space, and has no competition or predators, it can grow exponentially. This is because there are no limiting factors to control the population growth.<br /><br />## Step8<br />A grizzly bear can be a parasite, a competitor, and a predator, but not a mutualist. This is because mutualism involves a relationship where both species benefit, and a grizzly bear does not typically have this relationship with other species.<br /><br />## Step9<br />The factor that has the greatest effect on reproductive potential is reproducing earlier in life. This is because the earlier an organism reproduces, the more offspring it can produce over its lifetime.<br /><br />## Step10<br />Members of a species may compete with one another for resources. This includes food, water, and territory.<br /><br />## Step11<br />A robin that does not affect the tree in which it nests is an example of commensalism. This is a type of symbiotic relationship where one organism benefits while the other is unaffected.<br /><br />## Step12<br />Two species can be indirect competitors for food if they use the same food source at different times. This is because they are not directly competing for the same food source, but they are both using the same resource.
