2. Commensalism- one partner benefits and the other neither benefits nor is it harmed
3. Parasitism- one partner (the parasite) benefits and the other (the host) is harmed

Question 2

Name an eg. Of mutualism

Answer 2

Acacia-ant mutualism- the acacia trees provide a place for the ant to love, in addition the trees supply the ants with a protein rich food source for the larvae while in return the ants defend the trees against herbivores such as giraffes and insect herbivores

Question 4

How many vascular plants rely on this

Answer 4

95%?

Question 5

Give an eg. Of commensalism

Answer 5

Epiphytes plants particularly in forests use tree trunks and branches as surface on which to grow but do not take any moisture or food from the tree so they can grow up to the the higher Canopus to reach the sunlight

Question 6

Give an eg. If parasitism

Answer 6

Mistletoe is a parasite that obtains its moisture from a host tree while using its own leaves to manufacture food, it’s seeds are deposited on a new host plant by the mistletoe tyranny let, following digestion of the fruit
