How do biologists understand how predators are necessary to main tain healtly populations of prey animals?
In short terms: They don't. However, in many cases there are clear logical deductions to make based on previous experiments or observations in similar communities. Sometimes they also do field experiments where they fence off areas, keeping the predators out and "seeing what happens".
You should also be aware that predators aren't always necessary for prey to maintain healthy populations, but rather that this can be the case in certain communities, especially ones affected by top-down control (e.g. predator numbers decline, their prey boosts in population, the plants they eat get grazed to small numbers, another type of plant gains dominance, and the plant they used to eat gets outcompeted by the new plant, the grazing animals no longer have any food and get a severe population reduction due to starvation).

What is a shark biologist?
A shark biologist is a scientist who studies the biology, behavior, ecology, and conservation of sharks. They may conduct research on shark populations, habitats, and interactions with other species to better understand and protect these marine animals. Shark biologists often work to promote shark conservation and educate the public about the importance of these apex predators in marine ecosystems.
Predators are abiotic factors that limit the size of prey populations true or false?
False. Predators are biotic factors that influence the size of prey populations by consuming them. Abiotic factors are non-living elements like temperature, water, and sunlight that can also affect population size but are not predators.
What statement best describes bat populations in a stable ecosystem?
They are not limited by natural predators
What are the predators of roundworms?
What type of roundworms do you mean? roundworms in general and kind
What are the predators for archaebacteria?
Predators of archaea include other microbes such as certain protozoa and bacteriophages (viruses that infect bacteria). Some multicellular organisms, like nematodes and certain insects, can also feed on archaeal populations. Additionally, environmental factors such as extreme temperatures or high salinity can also impact archaeal populations.
How do predators and prey affect each other?
Predators and prey have a dynamic relationship where they influence each other's populations. Predators regulate prey populations by consuming them, which can prevent overpopulation and resource depletion. Conversely, prey populations influence predator populations by providing food sources that sustain them. This interaction helps maintain balance in ecosystems.
Why does presence of predators help keep an ecosystem stable?
The predators keep prey populations balanced.
Why doe the presence of predators help keep an ecosystem stable?
The predators keep prey populations balanced.

Can predators limit the size of populations by weakening their hosts causing disease or death?
Parasites
Why is it important that a population of predators exist in an area?
It is very important, because they contol the populations of their prey.
What are the predators of snails and how do they impact the snail population?
Predators of snails include birds, beetles, and some mammals like hedgehogs. These predators can help control snail populations by feeding on them, which can prevent snail overpopulation and damage to plants.
How Do Owls Keep An Ecosystem Balanced?
Owls are typically the top predators in an ecosystem, eating mice, etc. Predators are needed to regulate the other populations and keep the ecosystem at equilibrium.
What Mediterranean basin predators are there?
Some predators found in the Mediterranean basin include wolves, golden jackals, Eurasian lynx, and beech martens. These predators play important roles in maintaining the balance of the ecosystem by controlling prey populations.
