How does biodiversity affect ecosystem stability?

aleksklad [387]

Biodiversity completely depends on the ecosystem. The increase in biodiversity also leads to an increase in ecosystem stability.

Further Explanation:

Biodiversity is the term used for describing the variety of species found on earth. It can be animals, plants, microorganisms (bacteria and fungi), etc. the earth is rich in biodiversity; there are so many species that have to be discovered, whereas there are several species that have extinct. The entire living organism forms the ecosystem. It also includes their physical environment and the interpersonal relationship with them.

Species play a crucial role in the ecosystem. So the extinction or loss of particular species affects the perfect balance of the ecosystem. The ecosystem work in a cycle that means plants absorb the energy from the sun and produce food through the process called photosynthesis. The plant produced food is called the primary production, which is utilized by the myriad animals. The rate of primary production completely depends on the global food supply. It also increases the rate of climate change. The plants produce carbon dioxide at night time and remove it in the atmosphere. That decreases the variability of the environment and disturbs its original state.

The smallest contractile unit within skeletal muscle would correspond to the distance between which two points in the figure?

Tpy6a [65]

The distance between 1 and 7 spans a sarcomere correspond the structure at B is covered by the perimysium.

<h3>What is the smallest contractile unit within skeletal muscle?</h3>

A sarcomere comprises the segment between two consecutive Z lines and is the contractile unit of the muscle fiber, as it is the smallest portion of the muscle fiber capable of contraction and distension.

In this case, the distance between points 1 and 7 has the smallest structure of a skeletal muscle and corresponds to figure B.
