Parasites benefit their hosts is the true statement. Parasitism is a symbiotic relationship in which one organism (the parasite) benefits from another organism and this other organism is harmed by the parasite.
The others aren't true because:
- the organism that is harmed doesn'y adapt and evolve it still is vulnerable
- it is a fact that parasites change from hosts
- phoresy is an association between two species in which one transports the other. This does not include killing the host (is possible, but it is not a condition under which you can call something a phoresy).
Deforestation leads to fewer plants being available to conduct photosynthesis. Less oxygen is available for cellular respiration is a possible effect on the remaining plant populations.
<u>Explanation:</u>
- Deforestation and Photosynthesis are related to each other. Because if Deforestation occurs more photosynthesis will reduce.
- Cutting and burning down of the trees causes deforestation as it affects photosynthesis. Plants prepare food using photosynthesis.
- The plant takes carbon-di-oxide for the preparation of food and releases oxygen. Oxygen is required for every living thing in the world.
- As now World goes on deforestation and it should be seriously stopped.
