When predation occurs what is the organism that does the killing and eating called?

An interaction in which one organism kills and eats another organism is called predation. The organism that does the killing is the predator. The organism that is killed is the prey. If a prey population decreases, the population of its predator probably will decrease as well.

What is the organism that does the killing in predation?

In predation, one organism kills and consumes another. Predation provides energy to prolong the life and promote the reproduction of the organism that does the killing, the predator, to the detriment of the organism being consumed, the prey.

What is the species eaten in a predation called?

Keen senses are an important adaptation for many organisms, both predators and prey. A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

How predators may cause problems?

They grow more slowly, reproduce less, and populations decline. As predator populations increase, they put greater strain on the prey populations and act as a top-down control, pushing them toward a state of decline. Thus both availability of resources and predation pressure affect the size of prey populations.

How predation can affect communities?

Foundation species may also be dominant species. Predation can have large effects on prey populations and on community structure. Predators can increase diversity in communities by preying on competitive dominant species or by reducing consumer pressure on foundation species.

What was the first predator on earth?

Earth’s first big predatory monster was a giant underwater scorpion that reigned in the ocean almost half a billion years ago, well before the dinosaurs, scientists have discovered. The creature grew to 170 centimtres (5ft 7in) and had a dozen claw arms sprouting from its head, as well as a spiked tail.

What are some examples of interaction?

Examples are aspirin and motrin, alcohol and depressant, tranquilizer and painkiller. Synergistic interaction means that the effect of two chemicals taken together is greater than the sum of their separate effect at the same doses. An example is pesticide and fertilizer.
