Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb. Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers like photosynthetic protists use light energy to manufacture their own food.<span>

To primary consumers, as they directly eat producers and are next on the level of animals in an ecosystem.
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 dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype. By this logic, in heterozygous offspring only the dominant phenotype will be apparent.
hope this helps!

Climate change is the variation in the climatic factors and attributes like temperature and weather conditions of a region that can result in warming, ice melts, acidification etc.
Species cannot adapt fast enough to survive the change in their environment.
<h3>What is natural selection?</h3>
- Natural selection is the biological process of selecting the fit organism with better traits and qualities compared to another.
- It is a mechanism of evolution that help organisms to adapt to altered conditions and makes them more likely to survive in the conditions.
- Due to rapid climate change, the organisms are not able to adapt to the altered conditions.
Therefore, option C. is the correct option.
