Answer:
Herbivore that feeds on producers
Explanation:
The producers are plants at the bottom of the food web. These are eaten by herbivores, that are the primary consumers.
Herbivores themselves are consumed by carnivores, which are secondary consumers.
Sometimes, these carnivores can be consumed by top predators, like a shark, snake or eagle.
<u>Options and why they are right/wrong</u>
Carnivore that feeds on producers - carnivores do not feed on producers
Herbivore that feeds on producers - this is correct
Herbivore that feeds on primary consumers - primary consumers are animals and herbivores do not eat animals
Carnivore that feeds on primary consumers - this would be a secondary consumer
The purple spots on the colorless background of corn kernels observed by Barbara McClintock were the result of the transposition of the Ds elements out of the color gene.
<h3>What are the genetic elements found in corn?</h3>
- A transposable element is removed from one spot in the DNA and inserted into a different site in the DNA during the process of genetic transposition, which allows genes to shift their location on chromosomes.
- The first recognized genetic instability was caused by genetic transposition.
- The size of the tissue patch displaying the reversion phenotype increases as a reversion event happens earlier in the kernel development.
- Barbara McClintock saw purple dots on maize kernels with an otherwise colorless background.
- These spots were caused by the Ds components of the color gene being transposed.
- The wild-type (purple) phenotype manifests itself in cells where Ds from the color gene "C" sequence has been lost.
Hence, Barbara McClintock discovered purple patches on the colorless backdrop of maize kernels due to the transposition of the Ds elements out of the color gene.

The right answer is c. 3 to 10 million
The latest estimates are a bit more precise: there are 8.7 million living species (which is included in the range between 3 and 10 million), 6.5 million on land and 2.2 million in the water. Which is amazing, since there is more sea than land on our planet.
Researchers estimate that there are 7.77 million animal species, only 298,000 plant species and 611,000 species of fungi and molds.
