What is a Functional Response?
a change in the rate of predation by an individual predator in response to a change in the density of prey.
What is type ecological Type you functional response?
Type I functional response - no matter how many prey individuals are around, the predator individuals take them at the same rate.
What is 1 Functional Response?
- no matter how many prey individuals are around, the predator individuals take them at the same rate
What is Type II Functional Response?
as the number of prey individuals increases, the predators take them at an increasingly slower rate.
What is ecology Type III Functional Response?
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.
What is a Type III ecological functional response?
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
What is ecological Type II functional response?
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.
Is fungi a prey?
Yes My supermarket has several different types of mushrooms for sale (intended for consumption.)
What is the function of a cnidocyte cell?
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.
Why is there lag time between the increase in the prey population and the predator population?
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.
Why is the food that a bullfrog eats considered a part of its niche?
It is because a niche relates to the entire habitat, including weather, predators, and its prey.
