myrzilka [38]

Answer:

<em>Yes, the abiotic components interact with the biotic components in an ecosystem.</em>

Explanation:

The abiotic components are the non- living components of an ecosystem. The biotic components are the living components of an ecosystem. Abiotic factors such as sunlight, temperature etc directly affect the biotic components.

For example, the light of the sun is an abiotic component which provides energy to the biotic components, plants, to produce food. Soil is also an abiotic component which provides nutrients and water for the plants which are biotic components.

Answer:

Plants need a rigid structure. Animal cells have flexible cell membranes. So animal cells can have a variety of shapes, but plant cells can not, they have to take the shape of their cell walls. Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria.
