Pie

Answer:

They are inter-related with each other.

Explanation:

There is a great relationship present between evidence, conclusions and theories because evidences are those materials due to which a hypothesis can be verified and we can draw conclusion. When we repeat the same experiment and find out the same conclusion so it becomes theory and when these theories can't change with the passage of time, it becomes law. So evidence, conclusions and theories are inter-related to each other.

ANTONII [103]

The process that is used by producers to make glucose is called photosyntheis and the chemical process used by both producers ans consumers to make ATP ito contribute to the energy exchange is called cellular respiration.

Explanation:

Photosynthsis

Photosynthesis occue in the mesophyll tissue present in  leaves of plants .During photosynthesis the green plants or producers acquires CO2 from the atmosphere and utilizes water in presence of sunlight to produce glucose molecules along with the liberation of oxygen gas.

Cellular respiration

During cellular respiration the glucose molecules are oxidized to form energy in form of ATP along with the production of water and carbon dioxide.

    The O2 that formed during photosynthesis is inhaled by human beings for respiration whereas the CO2 that is produced as waste material inside our body is exhaled by us in the atmosphere.The CO2 is then used by the green plants to carry out photosynthesis.
