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.
The use of mitosis and meiosis varies among species due to their reproductive strategies and life cycles.
Meiosis, which produces genetically diverse gametes, benefits species by enhancing genetic variation and adaptability. Mitosis, on the other hand, generates genetically identical cells and is commonly observed in asexual reproduction for efficient cloning.
Complex life cycles often involve both processes at different stages. Environmental conditions and stability also influence the reliance on either mechanism. In stable environments, mitosis alone may suffice, while meiosis and sexual reproduction aid survival in challenging environments.

Answer:
ATP is an energy holder, or almost like a battery.
Explanation:
ATP stores chemical energy. Cells in your body use ATP to fuel cellular processes. This means ATP transfers energy from food to your cells, and you gain energy.
Answer:
ATP is the most abundant energy-carrying molecule in your body. It harnesses the chemical energy found in food molecules and then releases it to fuel the work in the cell. Think of ATP as a common currency for the cells in your body. The food you eat is digested into small subunits of macronutrients
Explanation:
Because that is just the way it works lol
Answer:
c) Electron microscopy
Explanation:
Electron microscopy (EM) is a technique for obtaining high-resolution images of biological and non-biological specimens.
