A. Photosynthesis and cellular respiration
B. Cellular respiration and decay
C. Decay and fossil fuel formation
Explanation:
Photosynthesis, cellular respiration, decay and fossil fuel formation are all processes that are part of the carbon cycle.
In the carbon cycle, carbon in different forms moves in the environment.
- During photosynthesis, green plants use carbon dioxide gas to manufacture their own food.
- Cellular respiration release carbon dioxide as waste product into the atmosphere.
- When plants and animals dies and decay, carbon dioxide is release from their tissues by the activities of decomposers.
- Fossil fuel formation removes carbon by accumulation of the organic matter of plants and animals.

Weathering (erosion), transportation, deposition, compaction. Essentially D is the correct answer.
As given in the graph, mutation in this gene causes a decline in the production of glucose as it obstruct the process of photosynthesis.
<h3>What is psaB gene?</h3>
P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1, and FX, are bound by PsaA and PsaB.
As given in the graph, mutation in this gene causes a decline in the production of glucose as it obstruct the process of photosynthesis.
Thus, the plant with the mutated psaB gene was dying.

I was looking for this one too.
Answer:
Primary
Explanation:
Ecological succession is the gradual change in the structure of a community or ecosystem. There are two types namely: primary succession and secondary succession. In primary succession, the change starts with no presence of life i.e. on a barren piece of land or rock. The pioneer species are organisms that have the ability to survive on bare rocks e.g lichens.
In the image attached, the succession starts with a BARE ROCK, and the first pioneer species are lichens before gradually moving into a climax community. Hence, this is an example of primary succession. Note that, in secondary succession, there is presence of SOIL.
