Ineed for both questions. i think i got the first one but i could be

Answer No 4:

Photosynthesis can be descried as a process in which carbon dioxide and water get converted into oxygen and glucose in the presence of sunlight. Energy from the Sun is essential for this process to occur. The light energy from the sun gets converted into sugars which are essential for providing plants with food. The sugar made during photosynthesis is also used for other cellular functions.

Answer No 5:

The non- photosynthetic organisms cannot make their own food. Hence, they feed on producers or other consumers. The initial source of energy on a food chain or food web are producers. As producers use light energy from the Sun to make glucose hence light energy is converted into usable energy for the producers as well as the consumers which eat the producers.

Also, as a result of photosynthesis ( which uses light energy) oxygen is produced. This oxygen is used for cellular respiration by the non- photosynthesis organisms. Hence, light energy is the initial energy source.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right
