Option D, it has a strong influence on the ecosystem
Explanation:
Keystone species are an essential part of an ecosystem and their functions/mark cannot be replaced by any other organism. Once the keystone species is removed from an ecosystem, the ecosystem struggles to sustain or it changes radically. A keystone species in majority of ecosystems/food web is a predator but this is not true in all ecosystems/or with all keystone species.
For example – there was a trophic cascade when the Gray wolves in the greater Yellowstone ecosystem were removed.
One way to remember this is when you are building a bridge there is one piece right in the middle that keeps the whole thing from collapsing that is called the key-stone. If a keystone species goes extinct then the rest of the ecosystem will crumble around it.
Its defensive, warning coloration is bright colors. Such as poisonous dart frogs, they are brightly colored in order to warn predators they are poisonous
Organisms differ in how they obtain energy, and they are classified as autotrophs or heterotrophs based on how they obtain their energy in an ecosystem. ... organisms that contain chlorophyll absorb energy during photosynthesis and use it to convert the inorganic substance carbon dioxide and water to organic molecules. Why?
