Which of the following statements concerning characteristics of predator/prey relationships is correct?
All of the following statements concerning characteristics of predator-prey relationships are correct EXCEPT: A rise in the population of prey is often followed by a rise in the population of predators.
What are the characteristics of a predator?
Predators exhibit traits such as sharp teeth, claws, and venom that enhance their ability to catch food. They also possess extremely acute sensory organs that help them to find potential prey.
What are some predator/prey relationships?
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words “predator” and “prey” are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.
Does the population of predators most often eliminate the population of prey?
A rise in the population of prey is often followed by a rise in the population of predators. B. A rise in the population of predators is followed by a decrease in the population of prey. The population of predators most often eliminates the population of prey.
What would happen to a population of predators if there was a sudden increase in food for the prey?
What would happen to a population of predators if there was a sudden increase in food for the prey? Predators could potentially enter into exponential growth which harms the prey a lot.
Why is a sudden increase in a predator population usually temporary?
Why is a sudden increase in predator population usually temporary? Predators may compete with each other for food. and die in the process. Others may just die because of old age and the population will level off.
What happens when predator population increases?
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.
What happens when predator population decreases?
The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species. When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other. When the predators are removed, prey populations explode.
What type of predator is a human?
Predators that exert a top-down control on organisms in their community are often considered keystone species. Humans are not considered apex predators because their diets are typically diverse, although human trophic levels increase with consumption of meat.
How can predators be classified?
One way of classifying predators is by trophic level. Organisms which feed on autotrophs, the producers of the trophic pyramid, are known as herbivores or primary consumers; those that feed on heterotrophs such as animals are known as secondary consumers.
Why do predators eat guts first?
Lions tend to eat the chest-area organs first (lungs, heart, liver). They chew a hole in the ribs to get to these tasty and most-nutritious morsels. This prevents stomach acids from spoiling the meat over the 3-5 days it will take the lion to finish eating the entire deer.
What animal does not eat guts?
In other words, the platypus has no stomach. The stomach, defined as an acid-producing part of the gut, first evolved around 450 million years ago, and it’s unique to back-boned animals (vertebrates).
What would kill a rabbit and not eat it?
Raccoons As scavengers, a raccoon can attack and kill a rabbit to harm it but not eat as raccoons only eat what’s already dead.
Do predators eat intestines?
They’ll eat udders, organs and muscle, sometimes leaving behind only skin, bones, and the stomach or intestines. They usually start by eating the internal organs except for the colon and intestines. The other possibility is that the cat was hit by a car and then scavenged by a smaller predator.
What predator does not eat intestines?
Many raptors will methodically and deliberately remove the intestinal tract of their prey before consuming it, a behavior that I’ve photographed several times with different species.
Do predators eat organs first?
In the natural world, predatory animals are known to value the organs of their prey and, for example, to eat the liver first because it is so densely packed with nutrients.
Do animals eat the guts?
Almost all carnivorous fish, reptiles and amphibians eat their animal prey whole. Depending on the hunger and fitness of the lion in the pride, they will also eat the intestines or, if they are consistently well fed, they may leave the very end of the large intestines for the scavengers.
Do coyotes eat guts?
Coyotes have ventured out at night and dined at the all you can eat gut pile smorgasbord. With full bellies, they head back for the safety and security of the thick stuff. Just like after a big Thanksgiving dinner it’s time for a nap.
What carnivore eats the most?
Blue Whale At up to 100 feet long and weighing 200 tons, it has a larger body and weighs more by far than any other mammal. The blue whale is a carnivore that eats krill, which are tiny shrimp-like creatures. Even at birth, a young blue whale is still the largest meat-eating mammal.
Do coyotes eat their entire prey?
Coyotes take their kill to a safe place to eat. They may carry their prey up to a mile before consuming it. They don’t leave much behind and tend to eat whatever they can fit in their mouth.
Why do coyotes kill but not eat?
Coyotes are known to be highly adaptable to both urban and suburban areas. While they’re generally assumed to kill to eat, it’s possible that they may adapt to their surroundings and begin killing for fun when food is easily available.
Will Coyotes come back to a Kill?
Usually though they will consume their meal where they catch it unless that area does not feel safe enough to them. Then they will take it to where it is safer for the coyote. If the pair of coyotes is dened up and have pups they may take their quarry back to the den for the pups to have.
