Describe two ways of measuring biodiversity. Explain the relationship between biodiversity and ecosystem stability. As part of y
Daniel [21]

Answer:

- Two predictors to measure biodiversity: Species Richness and Simpson's Index  

- Biodiversity increases ecosystem stability  

- It has been shown that natural ecosystems are more stable than monocultures, while isolated human populations are found in highly diverse ecosystems

Explanation:

Two major predictors to measure biodiversity are: 1-species richness and the 2-Simpson's index. The species richness is a count for the total number of the species in a given habitat and/or ecosystem; while Simpson's index is a similarity index that indicates the likelihood that two different individuals selected at random from a sample will belong to the same species, thereby also estimating the biodiversity of a habit and/or ecosystem. Simpson's index takes into consideration the number of species and the abundance of each species. Ecosystems with high diversity tend to be more stable and resilient than ecosystems with low diversity. Biodiversity increases ecosystem stability due to the species asynchrony, which is a strong driver capable of stabilizing multiple processes/functions in the ecosystems over time (e.g., the productivity of the ecosystems over time). In this regard, it has been shown that forests that are highly diverse in the number of species are more productive and stable under stress than monocultures (i.e., agricultural crops), while isolated human populations live in sustainable ecosystems, it is for that reasons that isolated tribes are only found in highly diverse ecosystems.

Which of the following situations or phrases most accurately describes the citric acid cycle?
Bond [772]

The correct answer is: B) "All roads lead to Rome"

Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.

Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
