20. If changing conditions lead to decreased oxygen levels in the stream, the carrying capacity of the stream for the trout will decrease. Oxygen level in water is therefore (an) ___________ with respect to the number of trout that a particular stream can support.

22. Disturbance of an ecosystem by human activity often has negative effects on the number of species, which is a measure of it's_______________.

I think the answers are
20. competition
22. i don't know

Please help quickly!

You don't have to be so rude. You could at least help me out.

rest in piece miss sue :(

ok sorry. but could somebody at least help me review some of this?

21 is missing rose

For question 20:

The term that describes the relationship between oxygen levels in the stream and the number of trout it can support is the carrying capacity. Carrying capacity refers to the maximum number of individuals of a particular species that an ecosystem can sustain indefinitely given the available resources. As stated in the question, if changing conditions lead to decreased oxygen levels, the carrying capacity of the stream for trout will decrease. Therefore, the oxygen level in water is inversely related to the carrying capacity for trout, meaning it is a limiting factor.

The correct answer for question 20 is limited with respect to the number of trout that a particular stream can support.

For question 22:

The missing term to complete the sentence is biodiversity. Biodiversity refers to the variety of different species, genes, and ecosystems within a given area or the entire planet. When an ecosystem is disturbed by human activity, such as habitat destruction or pollution, it often has negative effects on the number of species present. This decrease in species richness and diversity ultimately leads to a decline in biodiversity.

The correct answer for question 22 is biodiversity.

Carefully read your text again. Look especially for oxygen level trout. Also look for number of species ecosystem.

I already responded. Now check your text or look up the words in Google.

Ms. Sue was not rude. She's telling you to look at your original post, and then read and think.

And why all the shouting? Using all caps is rude online because it comes across as shouting.

=(

I wasn't aware that it was rude for a teacher to tell a student where to find answers.
