What major role does krills play in its ecoystem that would qualify it as a key stone specie?

They are important in the food chain because they feed on phytoplankton, and to a lesser extent zooplankton, making nutrients available to other animals for which krill make up the largest part of their diet. For this reason krill are considered a keystone species in the Southern Ocean ecosystem.

What major role does your species play in its ecosystem that would qualify it as a keystone species?

A keystone species is an organism that helps define an entire ecosystem. By keeping populations of mussels and barnacles in check, this sea star helps ensure healthy populations of seaweeds and the communities that feed on them—sea urchins, sea snails, limpets, and bivalves.

What major role does parrotfish play in its ecosystem that would qualify it as a keystone species?

Parrotfish are a keystone species on many coral reefs because they eat seaweed, also known as macroalgae, that would otherwise smother corals.

What major role do hummingbirds play in its ecosystem that would qualify it as a keystone species?

Hummingbirds

These are often referred to as keystone mutualists due to their mutual role. They are key agents of pollination and by doing so, aid in the growth and spread of certain plant species. A single hummingbird can pollinate over a large area.

Why is a starfish a keystone species?

Sea stars are important members of the marine environment and are considered a keystone species. A keystone species preys on animals that have no other natural predators and if they are removed from the environment, their prey will increase in number and may drive out other species.

What roles do species play in ecosystems?

Key Concept Any given species may play one or more of 5 important roles – native, nonnative, indicator, keystone, or foundation – in a particular ecosystem.

What role do starfish play in the ecosystem?

A starfish is a marine invertebrate. ... So starfish are predators, and they're probably the most important predator in the shallow ecosystem – so the depths where we would dive or swim. They eat basically anything that they can come across. Their feeding activities control the whole ecosystem.

Why are parrotfish important to the environment?

According to nature.org, the parrot fish are “colorful, tropical creatures that spend about 90 percent of their day eating algae off coral reefs.” “This almost-constant eating performs the essential task of cleaning the reefs, which helps the corals stay healthy and thriving,” the site said.

What is the importance of parrotfish?

Parrotfish play an increasingly important role in tropical reef ecosystems that suffer the depletion in reduction of coral cover. Parrotfish maintain coral reefs by consuming and removing macroalgae, which otherwise would cover the reef, causing it to become unhealthy and hindering it from growth.

What do parrotfish do?

Parrotfish are colorful, tropical creatures that spend about 90% of their day eating algae off coral reefs. This almost-constant eating performs the essential task of cleaning the reefs which helps the corals stay healthy and thriving.

What major role does a hummingbird have?

Hummingbirds (family Trochilidae) are amazingly adapted pollinators, and they play an important role in pollination. They have long, slender bills and tube-like tongues that they use to drink nectar from brightly-colored flowers; this gives them the energy they need to fuel their high metabolism.

What ecosystem do hummingbirds live in?

Hummingbirds are wild birds with a diverse habitat. They live in forests, deserts, lowlands, and mountaintops depending on the species.

What would happen if hummingbirds went extinct?

If hummingbirds went extinct, the mites could go extinct too because they would have no way of getting from flower to flower. Then the flowers, because they depend on the hummingbirds and mites to spread pollen, also go extinct.

What type of keystone species is a starfish?

The starfish Pisaster ochraceus is a keystone species in the rocky marine intertidal communities off the northwest coast of North America. This predatory starfish feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities.

What is special about starfish?

Starfish, also known as Sea Stars, are one of the most beautiful looking animals in the vast ocean. They have a surprisingly unusual anatomy, with no brain or blood, yet are able to digest food outside their body. Regenerating their own arms is perhaps one of the most useful things a starfish can do.

What are the advantages of a starfish?

A starfish's outer body contains a non-stick material with the ability to treat inflammatory human diseases such as arthritis and hay fever. The non-stick material achieves its curative abilities by repelling bacteria and viruses that cause diseases in human beings.
