Question 12 (1 point) When listing the characteristics of a species' niche they are largely based on a birth rate. b adaptations. predation.

## Step 1<br />A species' niche refers to its role in an ecosystem, including its interactions with other organisms and its environment. This concept is fundamental in ecology, a branch of biology. The characteristics of a species' niche are determined by various factors, including its physical habitat, the resources it uses, its interactions with other species (such as predation and competition), and its role in the ecosystem (such as its position in the food chain).<br /><br />## Step 2<br />Option (a), "birth rate," is more directly related to population dynamics rather than the niche of a species. While birth rates can affect the population size of a species, they do not define the species' niche.<br /><br />## Step 3<br />Option (b), "adaptations," is the most relevant to the concept of a niche. Adaptations are the physical or behavioral traits that have evolved in a species over time to allow it to survive and reproduce in its specific environment. These adaptations directly influence the species' niche, as they determine how the species interacts with its environment and other species.<br /><br />## Step 4<br />Option (c), "predation," is a part of a species' interactions within its niche but does not encompass all aspects of a niche. Predation is just one type of interaction that a species might have with other species, and while it can be a significant part of a species' niche, it is not the sole defining characteristic.
