Answer:

A. mRNA is made by RNA polymerase, using DNA as a template

Explanation:

An mRNA molecule is synthesized by RNA polymerase which uses DNA template to do so.  In eukaryotes, mRNA is specifically synthesized by RNA ploymerase II with the help of sigma factor and various transcription factors while tRNA and rRNA are synthesized by RNA polymerase III & I respectively. But in contrast to eukaryotes, in prokaryotes a single RNA ploymerase synthesizes mRNA as well as tRNA and rRNA with the help of sigma factor.

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.
