Answer:

"An oxygen-rich environment would cause a mass extinction of prokaryotes." Supports current scientific theories of how life might have originated on Earth.

Explanation:

The reacting power of oxygen increases rigorously in an oxygen- rich environment, which leads to huge fire ignition even with the slightest spark which is generally non hazardous at all. Many prokaryotic organisms do not need oxygen as they perform anaerobic respiration. Oxygen is dangerous for some prokaryotes.

There were some prokaryotic organisms who were giving out oxygen as waste. Such excess amount of oxygen was hazardous for the environment and hence mass extinction was required to keep a check on the excess amount of oxygen being released.

By changing the colour of body: Some animals such as grasshopper changes their colour to survive in places.
By modification of organs: some animals modify their organs to survive such as legs and beak of ducks are modified to survive in swim and search foods.

The importance of adaptation are:

It helps organism to live a longer life.
The adaptation helps to make an organism fittest to any environment.
The adaptation helps an organism to search foods and live their life.

Which of the following describes a way that decomposers are important to an ecosystem?

Aleksandr [31]

Answer:

Decomposers recycle essential nutrients back into an ecosystem

Explanation:

An ecosystem works thanks to the constant transformation of energy. The role of the decomposers will be to transform energy into something useful in the ecosystem. For example, The bacteria which will rotten the apples that fall from a tree onto the ground are recycling or making available this energy for other organisms to use it. As part of this example, the essential nutrients of the apples will be available to be reabsorved by the roots of the apple tree thanks to the transformation of energy done by the bacteria in the apples.
