How do plant cells and animals cells differ

Answers

The animal cell doesn't have chlorophlast, which gives the plant cell the green color. Animal cell doesn't have a cell wall. Most of the animal cells are round. Animal cells do not have plastids. Plant cells do not have lysosomes and cilia, though in rare occasions, there are. Centrioles are in some lower plant cells, and there are in animal cells. Plant cells have a rectangular shape.

Which best describes a bird’s role as it eats seeds? parasite, predator, habitat, or niche?

Answers

The answer is niche. Niche is the role and position of species in the environment. Thus, bird’s role as it eats seeds is the example of niche. Habitat is an area inhabited by a particular species, so bird's role cannot be habitat. Parasite is an organism that lives on/in another organism (host) at the expense of the cost. Also, predator eats its pray. If a bird eats seeds, it is not parasite or predator.

The word which best describes a bird’s role as it eats seeds is: D. niche.

In conclusion, an example of a niche is a bird’s role as it eats seeds.
