Which describes a population depending on an abiotic factor?
group of answer choices

a a hawk preys on a mouse.

b squirrels eat eggs from a bird's nest.

c coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above.

d a bean plant does not grow well because it is planted where there are many weedy plants.

is C). Coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above.

Explanation:    

In ecosystem, an abiotic factor is any non-living factor that influences the biotic factors and the population. Following are the examples of abiotic factors namely,  atmosphere, chemical elements, sunlight, wind, water. some are also given below:

Option C: is the only right option as it falls under the criteria of relationship between abiotics and biotc factors. Here abiotic factor is sinlight and abiotic factor is coral leaf. All other options are related to biotic factors (living things that shape an ecosystem). Examples of biotic factors are animals, plants, bacteria and fungi

Option A: description of predator and it's prey (biotic factor)

Option B: Also relationship between two living things i.e. squirrels and bird's eggs (biotic factor)

Option D: Comparison between two plants (biotic factor)

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

the correct answer is d
