The functional response relates the rate of prey consumption by an individual predator to the number of prey individuals.
a change in the rate of predation by an individual predator in response to a change in the density of prey.
Type I functional response - no matter how many prey individuals are around, the predator individuals take them at the same rate.
- no matter how many prey individuals are around, the predator individuals take them at the same rate
as the number of prey individuals increases, the predators take them at an increasingly slower rate.
as the number of prey individuals increases, the predators take them at a greater rate initially, but eventually take them at an increasingly slower rate; similar to a Type II functional response, but with a lag at the beginning.
Is like a Type II functional response, but with a lag at the beginning.This is realistic, because of(a) Density-dependent stimuli - predators sense prey by stimuli, and these stimuli often increase in strength with increasing numbers of prey individuals(b) Search image - smart predators often develop a search image for abundant prey items, but take some time to switch to a new prey item as a result
as the number of prey individuals increases, the predators take them at an increasingly slower rate. (a) Searching time - the time needed to find a prey individual. (b) Handling time - the time needed to subdue and consume a prey individual, and to recover from the experience. (c) Satiation - no matter how much a predator might want to eat another prey, sometimes it just can't.
Yes My supermarket has several different types of mushrooms for sale (intended for consumption.)
Cnidocytes are specialized cells found in cnidarians (such as jellyfish and sea anemones) that contain stinging organelles called nematocysts. The function of a cnidocyte cell is to capture prey or defend against predators by discharging venom-filled nematocysts in response to touch or chemical stimuli.
Because when a predator feeds on prey, the prey population goes down. When the prey population goes down, then so does the predator population. When the prey population recovers, then the predators soon after prey on the prey, and it repeats.
It is because a niche relates to the entire habitat, including weather, predators, and its prey.
