Answer:
Heterotrophic species that eat organisms from different trophic levels
Explanation:
Humans are examples of primary and secondary consumers because we are able to eat different types of living forms, thereby acting in the food chain as primary consumers (eating plants) in certain conditions and as secondary consumers (eating animals) in different conditions. Many heterotrophic organisms act at different levels by feeding primary producers and primary consumers based on specific trophic strategies. In consequence, the classification between primary and secondary consumers is arbitrary since it varies according to the trophic strategy adopted by the organism.
There are 2 types of photoreceptors rods and cones they react to light in different ways.
Rods-
Respond to low levels of light and are primary responsible for night vision.
They are poor at detecting fine details in an image and are not involved in colour vision.
Cones-
Respond to high levels of light and are primary responsible for our vision in well-lit conditions.
They detect fine details and are responsible for colour vision.
Answer:
Homologous structures
Explanation:
Features that are similar in structure, but appear in different organisms and may have different functions

scientific theories are like science stuff
but laws is like law stuff
