lesya [120]
The energy role of a grizzly is that is is a omnivorous consumer because it is not a producer.

A grizzly bear's diet consist of both plants and animals as it relies on the food it eats for energy consuptions. It is incapable of producing energy with photosythesis, hence it is not a producer.

According to the theory of endosymbiosis, the origin of chloroplasts probably involved: a. engulfing of small photosynthetic pro
DerKrebs [107]

Answer:

A. engulfing of small photosynthetic prokaryotes by larger cell

Explanation:

The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship.

Some Evidence for this is based on the following:

1. Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane.

2. The mitochondria are the same size as prokaryotic cells, divide by binary fission, and the mitochondria of some protists have Fts homologs at their division plane.

3. Mitochondria and chloroplasts have their own DNA that is circular, not linear.

4. Mitochondria and chloroplasts have their own ribosomes that have 30S and 50S subunits, not 40S and 60S.

5. Several more primitive eukaryotic microbes, such as Giardia and Trichomonas have a nuclear membrane but no mitochondria.
