The correct answer is option a. true.
The fossil fuels, including coal and oil are present very deep inside the earth. In the carbon cycle, only fixation of atmospheric carbon dioxide in the organic material takes place. This cycle does not involve the recycling of the fossil fuels.
The burning of the fossil fuels directly release carbon dioxide and other carbon compound in the atmosphere, which was not involved in the cycle when it was present deep beneath the earth and ocean. Hence, the burning of fossil fuels increases the amount of carbon in the carbon cycle.
Answer:
The flamingos will not be able to eat algae and shrimp, thus the food chain will slowly get unbalanced, and then everything will stop
Explanation:
Answer:
B. Stable ecosystems
Explanation:
The main cause of the biodiversity experienced in rain forests is largely due to the stable ecosystems that they enjoy.
A stable ecosystem is a sustainable one that does not change too much over the course of time.
Most organisms and the diverse life forms are easily nourished by the provisions made available by nature in such regions.
- Most rain forest receives a large amount of solar radiation and energy all year round as the sun is directly overhead here.
- This suggests that the producers have enough energy to cater for their own need and that of the organisms there in.
- The consumers and decomposers have sufficient food available all year round.
- This coupled with other factors whereby organisms have specially adapted to environmental conditions makes a rain forest very biodiverse with life forms.
- An unstable ecosystem cannot be biodiverse
Samuel ate some vegetable soup. <u>Digestion</u> process is at work to allow Samuel to break down the soup so that his body will be able to produce energy.
<u>Option: D</u>
<u>Explanation:</u>
There are majorly four steps in food processing in human body, these are ingestion, digestion, absorption and elimination. There are six major phases covered by digestion: ingestion, acceleration, mechanical or physical digestion, chemical digestion, absorption and defecation. The first of these procedures, ingestion, relates to the absorption of food via the mouth into the food canal.
Digestive system allow the transformation of massive insoluble food molecules into small water-soluble food components to dissolve them into the watery plasma of the blood. Many smaller particles are ingested into the bloodstream in certain species through the small intestine.
