Answer 8

Can you elaborate why you think it's C

Answer 9

Apologies for the confusion. Let's further explain the correct answer for Question 1.

The correct answer is C: Competition would decrease. Many ecosystems rely on wildfire to restore nutrients and germinate seeds. Therefore, wildfires will increase resources available, lowering competition.

In a forest ecosystem, competition between organisms, such as plants, for resources like sunlight, water, and nutrients, is common. Wildfires can have both direct and indirect effects on competition within the ecosystem.

When a wildfire occurs, it clears out vegetation, opening up space and reducing the number of individuals competing for resources. This decrease in competition happens because some individuals may be killed or their populations reduced by the wildfire. As a result, the remaining individuals have more resources available, as there are fewer competitors for those resources.

Additionally, wildfires play a crucial role in recycling nutrients and promoting new growth in an ecosystem. They release nutrients from burned plant material, enriching the soil. This increased availability of nutrients can lead to more abundant plant growth, providing additional resources for the remaining individuals.

Overall, the occurrence of a wildfire can decrease competition among individuals in a forest ecosystem by reducing the number of competitors and increasing the availability of resources.
