Answer and Explanation:

Corals are a type of invertebrate within the <u>phylum Cnidaria</u>. They live in colonies of many identical individual polyps.A set of tentacles surround a central mouth opening. They also have a simple, radially-symmetrical body containing a single opening that serves as both the mouth and anus. The body is made up of two layers of cells, separated by a jelly-like layer with no internal organ. The two layers of cells make a single cell surrounding the body.

Bioflix activity: cellular respiration and photosynthesis -- energy flow can you identify how energy flows through an ecosystem?
Alenkinab [10]

Answer:

Sun

Sun is the main source of energy on earth. About 40% light reach to the atmosphere some of which is filtered by ozone layers, water vapours and other gases. only 1% light is used in photosynthesis.

Photosynthesis

                         Producers contain chloroplast filled with chlorophyll molecules. when sunlight falls on leaves process of photosynthesis occurs which convert light energy into chemical energy in the form of glucose.

Respiration

                 Respiration occurs both in producers and consumers. in this process chemical energy (glucose) is converted into ATP, NADH and FADH2.

Decomposition

                  there are some organisms known as decompose s. they decompose dead bodies of plants and animals and convert complex molecules into simple nutrients with help of energy. in this way sun light energy is transferring in ecosystem in different forms.

inysia [295]

Answer:

<em>Geographic isolation</em>

Explanation:

Geographic isolation can be described as a term that describes the model of speciation in which a biological population becomes isolated from other members of the population and can no longer have gene flow with them.

The same scenario of gene isolation is occurring in the species of taods which live at the top of the mountains in southern Arizona. This population has become reproductively isolated fro all other species of toads within the mountain range.
