What is the relationship between aphid and ant quizlet?

Some species of ants “farm” aphids: the ants feed on a sugar-rich liquid (called honeydew) secreted by the aphids, and in return, the ants protect the aphids from predators. The ecological relationship between the ants and the aphids is: A. commensalism.

When two or more species live together in a close long term relationship it is called?

Symbiosis: A close and long-lasting association between two or more organisms of different species. Mutualism: A symbiotic relationship in which each organism benefits from the association.

What happened in Connell’s experiment with Chthamalus Stellatus and Semibalanus Balanoides?

He observed that Chthamalus occurs higher on the shore than Semibalanus, and suggested that it was stopped from living further down by competition with Semibalanus. He found that, where Semibalanus were removed, the Chthamalus did perfectly well. Figure 1 shows one of his many graphs of this experiment.

When two species compete the niche that each species ultimately occupies is its?

a) The competitive exclusion principle, also called Gause’s Principle, states that when two species compete for exactly the same resources (thus, they occupy the same niche), one is likely to be more successful. As a result, one species “outcompetes” the other species, and eventually the second species is eliminated.

What is the relationship between ants and aphids?

Several species of ants have a special symbiotic relationship with aphids- they farm them! Aphids feed primarily on the sap from plants and secrete a liquid called honeydew. This secretion is very sugar-rich, and quite favoured by ants as a food source.

What is the relationship between aphid and plant?

Aphids are among the most destructive insect pests on cultivated plants in temperate regions. In addition to weakening the plant by sucking sap, they act as vectors for plant viruses and disfigure ornamental plants with deposits of honeydew and the subsequent growth of sooty moulds.

What is Connell’s elegant field experiment?

On the Rocky sea coast of Scotland, Connel’s field experiment shows that the larger and the superior barnacles (Balanus) dominate the area which is intertidal and eliminates the smaller barnacles (Chthamalus) from that zone, Hence it shows competition exclusion.
