4. Which of the following statements is true?
A. Biodiversity provides additional resources that raise the carrying capacity of an ecosystem
B. Biodiversity increases an ecosystems ability to withstand changes
C. Biodiversity makes an ecosystem more difficult to destroy
D. Biodiversity provides additional resources of food for the weakest organisms in an ecosystem***
Actually I think B is a better answer
Yes, B.
Thx.

To determine which statement is true, let's examine each option and evaluate the validity of the claim:
A. Biodiversity provides additional resources that raise the carrying capacity of an ecosystem.
The carrying capacity refers to the maximum population size that can be sustained by an ecosystem over a long period of time. Biodiversity refers to the variety of species within an ecosystem. The presence of diverse species can indeed provide additional resources such as different types of food and habitats, which can support a larger population and increase the carrying capacity of an ecosystem. Therefore, option A can be considered true.
B. Biodiversity increases an ecosystem's ability to withstand changes.
Biodiversity plays a crucial role in enhancing the resilience and stability of an ecosystem. In diverse ecosystems, different species occupy various ecological niches, and they may have different responses or tolerances to environmental changes. This diversity helps to ensure that even if some species are negatively affected by changes, others may be more resilient and can compensate for any losses. Therefore, option B is also true.
C. Biodiversity makes an ecosystem more difficult to destroy.
The presence of diverse species in an ecosystem can provide various ecological functions, such as nutrient cycling, pollination, and pest control. A higher level of biodiversity can contribute to the overall functioning and productivity of an ecosystem. Additionally, the extinction of species can disrupt these ecological processes and lead to negative impacts on the ecosystem's stability and resilience. Therefore, option C is true.
D. Biodiversity provides additional resources of food for the weakest organisms in an ecosystem.
This statement suggests that biodiversity specifically provides additional resources of food for the weakest organisms in an ecosystem. While it is true that diverse ecosystems often have a greater availability of food resources, it is not solely limited to supporting the weakest organisms. In fact, the presence of diverse species can lead to complex food webs and interconnected relationships, where various organisms can find their niche and acquire food resources. Therefore, option D is not entirely accurate.
Based on the evaluation of each statement, we can conclude that options A, B, and C are true, while option D is not entirely accurate.
