The complete question is:  

Which of these processes produces oxygen? A) burning coal for heat B) respiration in animals C) photosynthesis in plants D) operation of an acetylene torch

Answer: Photosynthesis in plants

Explanation:

The production of oxygen on earth is possible only when there is a process of photosynthesis on earth. The process by which the autotrophs make food is responsible for food and oxygen on earth.

The production of carbohydrates takes place in the presence of sunlight and carbon dioxide.

This process is also responsible for the production of oxygen in the environment.

If predators A and B prey upon the same species and predator A is eliminated, the population of predator B will likely _________
Allushta [10]

Answer:

Increase

Explanation:

The predator is a type of animal or bird species which kill other animals to obtain its food. The prey is the animal which is killed by the predator. According to the given situation, if the predator species A is eliminated, the population of the predator B will likely increase because there will be no competition between the two species for the same prey. And the chances of predator B obtaining the prey will increase. Hence, the population will increase.

<u>Answer</u>: predator and prey

<u>Explanation</u>:

The described graph illustrates the cycle of a predator and prey population.  The population curves for predator and prey are not synchronized with each other and their amplitudes differ.

Changes in the prey population will not result in immediate or exactly identical changes in the predator population.

In the attached image, the red line represents the prey population and the blue the predator population. As it can be observed, when the prey population increases in size, the predator population size increases too.

However, this increase is not of the same size and is delayed in time. The predator population will continue to increase even though the prey population has started to decrease.

This has to do with the fact that the adult predators mated and gave birth when the food availability was still high. However, these new young individuals will not survive and reproduce due to decreasing prey. As the prey continues to decrease, more and more predators will perish.

The same cycle will then repeat over and over again.
