Heterotrophs help in maintaining a balance in the ecosystem by providing organic compounds for autotrophs. Certain heterotrophs such as fungi help in reducing decomposed plant and animal material. This recycling activity is important in reducing waste in the environment.

Changes in the trilobite exoskeleton can be attributed to changing environments and competition for survival
Answer:
The correct answer will be- ATP binds to the myosin head
Explanation:
The muscle contraction is associated with the ATP binding to the myosin head which triggers the formation of the cross-bridge between the myosin head to the actin on muscle and pulling the sarcomere.
The cross-bridge cycle pulls the sarcomere thin filaments which require energy provided by the ATP as ATP when binds the mysoin head allows the detachment of the myosin to the actin.
Thus, ATP binds to the myosin head is the correct answer.
The statement that correctly pairs biotic factors with an effect on the biosphere is that biotic factors would decrease the oxygen in the soil.
<h3>What are biotic factors?</h3>
Biotic factors of an ecosystem refers to the living components of that ecosystem. Biotic factors include the following:
Biotic factors make use of oxygen in the atmosphere to perform the process of respiration, hence, their presence will cause a decrease in the oxygen content.
Therefore, the statement that correctly pairs biotic factors with an effect on the biosphere is that biotic factors would decrease the oxygen in the soil.

The forester made an observation that the forest had mostly mature hemlock and very few young hemlock. This is common for outdoors scientists to make observations on the part of the natural world that is their field of study, and then draw conclusions from these observations. For example, the observation that the western edge of North and South America has a string of volcanoes or the ring of fire, plus the concordance between the east coast of South America and the western coast of Africa let first to the theory of continental drift and finally to plate tectonics. Similarly, the paucity of young hemlock and the existence of mature hemlock could also spark a conclusion, such as maybe the mature hemlock were diseased so couldn't create new offspring or perhaps a fire had wiped out the young ones, as two possible explanations which would depend on the actual circumstances observed by the forester.
