Question
Chapter 56, Problem 3S
Summary Introduction
To explain:
The reason behind the worry of the ecologist regarding the potential effects of the loss of the species on an ecosystem for other reasons.
Introduction:
The ecosystem consists of various species which interact with each other in the food web. The effects in one of the species in one trophic level affect the species in the other trophic levels. This process is known as the cascade effect.

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.
Question: Based on this scenario, what is the most significant role of sea otters in the marine community? Why it’s important?

- Give an example of a specific function of necessary for life or reproduction in the human that is maintained by a feedback loop. Describe the system, giving the stimulus, the response, and how that maintains function of the system. describe a real or hypothetical condition caused by disruption of this system.arrow_forwardDetermine if each statement is correct or incorrect: 1. 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_forwardDescribe how change, large and small, has an effect on the ecosystem with examples( for large change and small change)arrow_forward
