Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forwardNOTE: The image you need to see in order to answer this question is attachedA developer owns the property encompassing the three habitats above. By law, one of the habitats must be left intact to satisfy the zoning laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer suggests that Site C should be saved. Which of the following choices best justifies this decision?Responses A) Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future generations of animals. B) Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it. C) Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species. D) Site C has more unique species in it than either Site A or Site Barrow_forward
- A conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction.
