based on the living things in the pyramid, tell me what examples would fit into these categories: primary producers, primary con
algol [13]

Answer:

- Oak trees: primary producers

- Caterpillars: primary consumers

- Blue Jays: secondary consumers

- Hawks: tertiary consumers

Explanation:

A trophic pyramid, also known as ecological pyramid or energy pyramid, is a graphic representation that shows the relationships between different types of organisms (i.e., producers and consumers) at the trophic levels of an ecosystem. The primary producers are autotrophic organisms that obtain energy from sunlight and chemical compounds from nonliving sources (e.g., photosynthetic plants, algae, etc). The primary consumers are organisms that eat primary producers (e.g., herbivores), while secondary consumers are organisms that eat primary consumers (e.g., omnivores). Moreover, tertiary consumers are predators and/or omnivores that eat secondary consumers (e.g., hawks). Finally, decomposers (e.g., bacteria) are organisms that obtain nutrients and energy by breaking down dead organic material (i.e., dead organisms) at all trophic levels into nutrients.

Answer:

Please see my answer below.

If you like my response you can mark it as brainliest.

If you have any doubts (no joke) you can reach out to me in the comments.

Explanation:

<em><u>The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.</u></em>

Explain how geographic isolation can result in the formation of a new species
Vesna [10]
<span>Geographically isolated populations may live under different environmental conditions, which can lead to each of these separated populations adapting differently to these different conditions. Given enough time, these little changes can lead to those populations diverging into distinct species after so many successive generations. </span>
