Question 17
A food chain is a group of organisms connected to each other through their feeding habits. One organism is
consumed by a second one, which in turn is eaten by a third. The energy in virtually all food chains is first derived
from the Sun. As each organism grows and is consumed, only about 10 percent of the Sun's energy is transferred
to each subsequent organism in a food chain. People who live in poorer regions of the world where food is scarce
eat relatively little meat and depend principally on grains and other plants.
Based on these ideas, which of the following statements best supports eating habits observed in poorer regions of
the world?
Plants take up less space than animals
O It is easier to raise plants than it is to raise animals
There is a higher percentage of vegetarians among poor populations
O Plants store energy as carbohydrates which have more energy than fats
O 90% of the energy in plants is not transferred to the animals who eat them

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
