Answer:
As the graph is not provided, lets try to answer the question generally.
Explanation:
Human activities are known to be threatful and harm biodiversity in several ways.
Humans activities like deforestation results in many species from losing their homes. These species are not able to survive and hence become extinct.
Human activities such as fragmentation cause the genetic diversity to become lowered for organisms of a species. As a result, a disaster such as a disease results in killing all the organisms of a species present in a community.
Answer:
<h2>D</h2>
Explanation:
Photosynthesis occurs in plants and in some other autotrophs, in which they synthesize their food own-self in the presence of sunlight.
They take CO₂ from environment, water from roots and light form sun. Then they produce carbohydrate and O₂.
Chlorophyll capture sunlight and convert this into chemical energy, through which sugars are produced.
Plants produce O₂ which animals use in their respiration.
Answer:
Pyruvate take place after the process of glycolysis.
Explanation:
Pyruvate as intermediate take place in the process of photosynthesis after glycolysis process. One glucose molecule is converted into two molecules of pyruvate. This pyruvate molecule then converted into acetyl CoA, which is a two-carbon molecule. A molecule of coenzyme A is a very important reactant for this reaction, which produces a molecule of carbon dioxide and reduces a NAD+ to NADH.
