Parasitism
Explanation:
Parasitism is the form of mutual relationship between two organisms which occurs in such a way that one organism always get benefit and the other always gets harm. The one getting harm may or may not be killed due to it.
There are many common parasitic relationships we see in eco system.For example, when a tick sucks blood out of a dog. it is causing harm to dog by decreasing the content of blood however getting benefit for itself since blood is its food and the nutrients present in blood are source of energy for tick.
Similarly, Malaria is caused in human by a parasite called plasmodium. It enters into the blood and causes a disease called Malaria which can even lead to the death of affected individual,the parasite itself stays healthy and gets benefit.

Respiration is process where plant produce heat
Explanation:
Respiration is essential component for every living thing this. Respiration help living thing get energy and stay alive. In plant cellular respiration is used to convert nutrient which is present in soil and this process can be understand as a cellular activity. In plants seeds play vital role.
The basic difference between respiration and photosynthesis is in respiration plant consume nutrient for survival and alive plant cell but in photosynthesis plant is able to make their own food. In respiration only plant produce heat energy
<u>The formula of Respiration:
</u>
Oxygen + glucose – Carbon dioxide + water + heat energy
<u>The formula of Photosynthesis
</u>
Carbon dioxide + Water + Sunlight – Oxygen + glucose
