Rhizobia are bacteria that live on the roots of some plants, such as legumes like pea plants. Rhizobia convert an element in the atmosphere into ammonia. Identify and explain the type of relationship this represents

• It is parasitism because the bacteria absorbs food from the pea plant

• It is commensalism because the bacteria and pea plant don't harm each other

• It is competition because the rhizobia and pea plant both need the limited amount of available nitrogen

• It is mutualism because the bacteria receives carbon from the pea plant, while the plant uses the ammonia to make amino acids

A species of insect is newly introduced into the United States from the Philippines. This insect becomes established, laying its eggs on the leaves of oak trees. How can a biologist determine if the relationship between the insect and the oak tree is commensalism, mutualism, or parasitism?

• If the insect benefits, the relationship is parasitism

• If both the insect and the tree benefit, the relationship is commensalism

• If the insect benefits and the tree neither benefits nor is harmed, the relationship is mutualism

• If the insect benefits and the tree neither benefits nor is harmed, the relationship is commensalism
