Question

instructions: place a ; next to things you already knew,! next to things you found interesting and? next to things you did not fully understand. highlight key information as you read. species richness and relative abundance are the two factors that are considered when measuring species diversity. explanation: species richness and relative abundance are the two factors that are considered when measuring species diversity. species richness refers to the number of species in an area. species abundance refers to the number of individuals per species. relative species abundance is how common a species is relative to the other species in a defined location. for example, in the image below, we can see that these two communities are composed of the same species and are identical in regards to species richness. they have four different species of trees. however, they differ in regards to relative species abundance: community 2 is mostly composed of species a. species a has high relative species abundance compared to species b, c, and d. species richness and species abundance are factors that are used to determine how much biodiversity an area has. to conclude, the number of species factors into species diversity but also the number of individuals in each species is also considered. both affect species diversity. 1. define species richness in your own words? 2. define species abundance in your own words? 3. define relative abundance

Explanation:

1. Species richness is the count of different species in a given area.
2. Species abundance is the number of individuals within each species.
3. Relative abundance is how common a species is compared to others in a specific location.

Answer:

1. The number of different species in an area.
2. The number of individual organisms of a species.
3. How common a species is relative to other species in a defined place.
