Answer:
Changes in the basal levels that are on the bottom of the food chain.
Explanation:
Trophic levels are represented by steps in the food chain. In a simplified diagram, the first basal level is represented by primary producer organisms that include plants and algae. The herbivores are localized in the second place, while in the final levels it is possible to find carnivores and predatory species. It is well known that the changes in the basal trophic levels of this chain (i.e., changes in the first and the second levels) may alter the equilibrium of the food chain and consequently have effects on the stability of the ecosystem.
Cell respiration occurs in animal cells and not plant cells.
Photosynthesis uses chemical energy as energy source, and cell respiration uses light energy.
Photosynthesis uses light as energy source, and cell respiration uses chemical energy.
Correct answer: Photosynthesis uses light as energy source, and cell respiration uses chemical energy
Photosynthesis is a light dependent process in which green plants and certain other organism convert light energy in to chemical energy. In this process sunlight is uses to to convert water and carbon dioxide into ATP molecule which are needed for growth.
Cellular respiration is metabolic process that occurs inside the mitochondria of the cell to convert biochemical energy which is derived from nutrients into ATP (Adenosine triphosphate) and removal of waste products.
Photosynthesis uses light as an energy source, while cell respiration uses chemical energy. Therefore option d. is the correct answer.
The correct statement that distinguishes photosynthesis and respiration is:
Photosynthesis uses light as an energy source, and cell respiration uses chemical energy.
In photosynthesis, plants convert light energy into chemical energy, specifically glucose. This process occurs in the chloroplasts of plant cells.
On the other hand, cell respiration is the process by which cells break down glucose to release energy in the form of ATP (adenosine triphosphate).
This process occurs in both plant and animal cells, specifically in the mitochondria.
Therefore, photosynthesis uses light as its energy source, while cell respiration uses chemical energy.
Therefore option d. is the correct answer.

B. Pollution
C. Invasive species
D. Climate change
The correct answer is A. Healthy ecosystems. The remaining three are actually quite the opposite and they destroy the healthiness of ecosystems. A healthy ecosystem is not polluted and has balance between species which in turn ensures that there's no climate change because there's nothing to affect it.
Carbon bonding is primarily covalent. Carbon shares electrons with other atoms to fill its valence shell. For example, in a carbon dioxide molecule, carbon forms double bonds with two oxygen atoms.
The question asks about the nature of carbonbonding. Carbon bonding is almost entirely covalent. This means that carbon forms bonds by sharing electrons with other atoms in order to fill its valence shell, or outermost energy level. For example, in a molecule of carbon dioxide, carbon forms double bonds with two oxygen atoms, sharing two pairs of electrons with each.
