Final answer:
A niche is the role a species plays in its ecosystem, involving their interactions with the biotic and abiotic factors of the environment.
Step-by-step explanation:
A niche is the role a species plays in its ecosystem. It includes the ways that the species interacts with the biotic and abiotic factors of the environment. An organism's niche involves its sources of energy, how it obtains food, and how it interacts with other organisms. A niche also includes the organism's role in recycling nutrients.
Each correct response is explained below:
C. It is the food a life form eats: The kind of food an organism eats is part of its niche. This could refer to the specific kinds of animals, plants, or other foods it eats to get energy and nutrients. For instance, a lion's specialty includes benefiting from herbivores like zebras and wildebeests.
D. It is the means by which the creature lives: An organism's behavioral and survival strategies are also included in its niche. This includes things like how it hunts, how it reproduces, how it moves around, and how it interacts with other organisms. For example, a nighttime creature's specialty includes being dynamic around evening time and having variations for low-light circumstances.
E. It's the place where the organism lives: The environment wherein a creature lives is a fundamental piece of its specialty. This alludes to the particular actual climate wherein the organic entity can be found, including the environment, geological area, and the biotic (residing) and abiotic (non-residing) factors present. For instance, a desert-dwelling organism's niche is in arid environments, while a marine organism's niche is in the ocean.
