Answer:
Ecosystems are influenced by both biotic and abiotic factors. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.
Answer:
All animals need oxygen to make energy from food. We get this oxygen from the air that we breathe. In order to get the oxygen into the blood where it can be transported to the rest of the body, the air travels through a system of organs called the respiratory system. When you inhale, air enters the body through the nose or the mouth. From there it passes through the pharynx, which forces air into the trachea and food into the esophagus. The air travels down the trachea into two branching tubes called bronchi and then on into the lungs. In the lungs oxygen from the air enters the blood. At the same time, the waste gas carbon dioxide leaves the blood and then leaves the body when you exhale. Some water vapor also leaves the body when you exhale, which is why mirrors get foggy when you breathe on them. The diaphragm is the muscle that controls the lungs. It is important to keep the respiratory system clear so oxygen can keep flowing into your body. If something gets in your nose and irritates it, you sneeze. If something gets in your trachea or bronchi and irritates it, you cough. If something irritates your diaphragm, you hiccup. Finally, if the brain thinks you are not getting enough oxygen, then it forces you to yawn.

"Tree bark is part of the vascular system" is an incorrect statement about tree bark, since almost all of the vascular properties of the tree take place inside the trunk.
All nitrates are soluble, so whatever amount is not taken up by plants in a field is washed away into groundwater and, eventually, into rivers, streams, ponds, and lakes. In these bodies of water, the nitrates become sources of food for algae and other plant life, resulting in the formation of algal blooms.
This could impact the population by gene flow that would increase between the two halves, and speciation would not occur.
<h3>What is Speciation?</h3>
Speciation may be defined as the process of formation of new species from a parental one. It occurs when members of similar populations no longer interbreed to produce fertile offspring within their natural environment.
The complete question is as follows:
- Traits that had developed through mutation would still exist in only one of the halves.
- Speciation would still occur because the two halves would be too different genetically to interbreed.
- The two halves would be reproductively isolated.
- Gene flow would increase between the two halves, and speciation would not occur.
Speciation requires time for genetic variations and mutations to occur. It makes the organism's reproductive isolated and hence the process of speciation may take place.
Therefore, the correct option for this question is D.
