Imperatoxin's effect on prey is that it immobilizes the prey. This allows for the insect to move in and kill the prey.
Color effects survival of prey because it allows the prey to hide in the environment or to scare away predators. This can help the prey to survive.
Basically, the prey overpopulate. Way too much prey around without anything to even out the numbers.
they leave or the die out
The predator eats (a benefit), and the prey is eaten (a harm).

Within certain species, the pros to group living triumph the cons. Group living can increase food gathering success and more achievement of avoiding predators, which in many cases makes the issues of competition and disease spread less imminent. Group living has many different assets to safety against predators. The three we are focusing on are the dilution effect, the confusion effect, and the odd prey effect. In the dilution effect, an individual's chance of being captured decreases as group size increases, often because the predator takes only a single or a limited number of prey on each attack. In the confusion effect, predators find it difficult to focus their concentration and pursuit on a specific individual prey animal when a large number of prey are escaping from predation at the same time, going in different directions, making a lot of noise, etc. It is difficult to focus on the stimuli coming from one prey because of the interference from all the stimuli coming from other escaping prey. The confusion may slow the predator down sufficiently that all of the prey are beyond successful pursuit distance before the predator is able to concentrate its efforts on any one prey animal, lowering the risk of capture for each prey individual in the group. In the odd prey effect, any prey that differs in a conspicuous way from the others in its group is more likely to draw a predator's notice, leading to an increased chance of its being attacked and captured.
Mainly through secondary means, when the owl's prey animals get scarcer.
Pumas do not have a major impact on their environment besides taking the prey they need to eat.
The poison caused by Cnidocytes (cells unique to the phylum cnidarians) causes paralysis. This allows the members of the phyla to safely consume larger prey.
1. The predation coefficients tell us what the outcome of each encounter is, on average a. The only significant outcome for the prey is whether it lives or dies (1) B1 is the proportion of encounters that result in the death of a prey individual (2) the right-hand side (RHS) of the prey equation is the effect of predators "cropping" off prey and slowing geometric growth b. The significant outcomes for the predator are a successful kill AND the production of offspring (1) B2 is the proportion of encounters that result in the death of a prey individual (B1) multiplied by the proportion of a new predator individual contributed by a prey individual (2) the RHS of the predator equation is the effect of prey "rescuing" the predator from geometric decline 2. N1 N2 is the probability of encounter of predator and prey a. This means that as the number of predator individuals and/or the number of prey individuals increases, so does the chance of them bumping into one-another.
Henfrayyy:57 minutes agoIf natural selections deselects the prey with qualities that can make it a worthy adversary to the predator, the predator's chief source of food will diminish and with it the predator. In consequence, the surviving prey will increase in population. The net effect is that the predator-prey balance will be upset.
lets say that theirs only predators and not so many prey than then all the animals well be decreasing
