This model chose to include certain features and exclude other features. For example, this simulation only includes rabbits, wol

ves, and grass but there are other predators of rabbits and other food sources for rabbits. Why do you think the creators focused on these data elements and not others

The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.

In the ecosystem, the living and non-living things interact over time leading to exchange of energy.

A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.

The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).

The energy flow is indicated with an arrow thus,

grass ---> rabbit -----> wolves.

Food chain, therefore includes linear sequence of organisms.

Food web on the other hand illustrates a complex feeding relationship within the ecosystem.

The food web is made up of a prey that can be eaten by more than one predator.

Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.

kmf Of the 40 specimens of bacteria in a dish,3 specimens have a certain trait. If 5 specimens are to be selected from the dish
almond37 [142]

Answer:

\frac{C^{3}_1* C^{47}_4}{C^{40}_5}

Explanation:

It is given that out of 40, total 5 specimen are selected.

Thus, the number of ways in which 5 specimens are selected from a given sample of 40 is given by

C^{40}_{5}\\

Number of specimen with certain trait is equal to 3.

Now, total 5 specimen are selected out of which one specimen is selected from the set of specimen that has certain trait (i.e out of 3) while the remaining four specimen will be selected from the rest 40-3=37 specimen.

Thus, the probability of choosing only 1 of the 5 specimens with the trait is equal to

\frac{C^{3}_1* C^{37}_4}{C^{40}_5}

How is a raft different from a typical ecosystem when considering carrying capacity?
harkovskaia [24]

Answer:

Explanation:

A raft is a flat-bottom structure made of planks or barrels that has the capacity to float on water. While an ecosystem is a community of living organisms (biotic) interacting with there non-living (abiotic) environment as an ecological unit.

A raft by design cannot withstand much load because of it's size or can only accommodate  only one type of organism at a time but an ecosystem generally accommodates a community (different organisms), hence the carrying capacity of an ecosystem is way larger than that of a raft and indeed a raft can be part of an ecosystem at some point
