Decomposers, as the name suggests, decompose dead plants or animals into simple compounds. They feed on dead producers from the first levels or consumers from other three levels. Breaking them down, decomposers release nutrients that producers can use.
In an ecosystem with four levels, the first level are producers, such as plants and algae. On the second trophic level, there are primary consumers, herbivores that eat plants, for example, a deer, a rabbit, a grasshopper. The next trophic level belongs to secondary consumers that eat herbivores, for example, a wolf, a fox. The highest level is tertiary consumers that eat carnivores, for example, a bear, an eagle.
There's been a lot of bad news for polar bears recently. In 2007, for example, scientists reported that if global warming continues unabated, the population could drop two-thirds by 2050.
The answer is cholesterol
Answer:
Is released into the air through stomata
Explanation:
Oxygen and hydrogen both exists as gaseous molecules in the atmosphere. However, one of them (oxygen) is a product of photosynthesis while the other (hydrogen) is one of the constituents of the molecule that starts the process of photosynthesis.
According to this question, the X used in the attached diagram is the role of oxygen in photosynthesis. Oxygen is released as a product of photosynthesis and goes out of the plant into the air via the STOMATA. Hence, the gas released into the air via stomata is OXYGEN.
