Which of following is not essential part of virus?

Answers

Envelope is not essential part of virus (option B)

What is virus?

A virus is a small, infectious agent that can replicate only inside the cells of living hosts. Viruses are not considered living organisms because they do not have their own metabolism or cell structure.

The essential parts of a virus are:

  • Nucleic acid: This is the genetic material of the virus, which can be either DNA or RNA. The nucleic acid carries the instructions for making new viruses.

  • Capsid: This is the protein coat that surrounds the nucleic acid. The capsid protects the nucleic acid and helps it to attach to host cells.

which statement best describes the difference in species diversity between an ecosystem beginning the process of primary succession and one beginning the process of secondary succession?

Answers

Answer | Explanation: The difference in species diversity between an ecosystem undergoing primary succession and one undergoing secondary succession can be described as follows:

1. Primary Succession: In primary succession, an ecosystem develops in an area that was previously devoid of life, such as a newly formed volcanic island or a bare rock surface. As the ecosystem starts from scratch, the process is slow, and the initial species colonizing the area are usually hardy pioneer species, such as lichens and mosses. These species have adaptations that allow them to survive in harsh and barren conditions. Over time, as the ecosystem progresses through different stages, more complex and diverse species gradually colonize the area. Therefore, species diversity is initially low in ecosystems undergoing primary succession.

2. Secondary Succession: Secondary succession occurs in an ecosystem that has been disturbed or disrupted, but where the soil and some remnants of the previous community remain. Examples of disturbances that lead to secondary succession include forest fires, clear-cutting, or abandoned agricultural land. In secondary succession, the recovery process is faster compared to primary succession because there is already a foundation of soil and existing species. As the ecosystem regenerates, a variety of species, including both early-successional and late-successional species, can quickly recolonize the area. This leads to a higher initial species diversity in ecosystems undergoing secondary succession compared to primary succession.

In summary, the main difference in species diversity between an ecosystem in primary succession and one in secondary succession is that primary succession starts with low species diversity and gradually increases over time, while secondary succession begins with higher species diversity due to the presence of soil and remnants of the previous community.
