What is heterotrophic nutrition?

Answers

Answer:

Type of nutrition in which organisms depend upon other organisms for food to survive.

Explanation:

Students in a biology class were discussing outbreaks of food-borne illness. Modern practices of refrigeration are aimed at curbing (limiting) these bacteria. They wanted to know exactly what happened to bacterial colony growth at varying temperatures. The teacher explained that scientists study bacteria in the laboratory by counting colonies that grow on plates filled with agar, which is a nutrient substance. “Design” an appropriate experiment that would test the effect of temperature on bacterial growth. You would have a period of 5 days to conduct an experiment.

Answers

Answer:

I know this isn't a big help answer, but you could use it as a start. You could say something like "I tested it in multiple different temps. including .... (any temps. you want) Then say how all of thoose different temps. changed the bacteria." I hope it helped! :)

Explanation:

Most of the foodborne diseases are caused by those bacteria that can grow well and infect food at normal temperatures, and their population can be controlled by lowering the temperature or raising the temperature too high, which can degrade their cell walls.

What is the effect of temperature on the bacteria?

There are numerous bacteria that can infect food and cause foodborne disease when consumed by humans, resulting in diarrhea, stomach aches, and other symptoms. Because most of these bacteria grow at room temperature, keeping food at that temperature degrades it faster, so foods are kept and stored in the refrigerator. This low temperature keeps the cellular activity of bacteria low; as a result, the bacteria cannot produce toxins or grow their population.

Due to this, the refrigerator stores the food for a longer time. Different strains can be kept and stored at different temperatures on an agar plate, but a strain present at a low temperature will produce far fewer colonies than one present at a room temperature. Further the growth depends upon the types of bacteria.

Hence, by refrigerating the food, cellular activity is seized and controlled.

What type of consumer do you think this coyote is? Can you tell from the photo that the coyote is not an omnivore?

Answers

Answer:

Carnivore.

Explanation:

Based on the picture alone, the coyote is eating meat, which would make it a carnivore.

Cayote is a tertiary consumer.

The photo alone cannot tell us cayote is not an omnivore.

Tertiary consumers are organisms on the fourth trophic level of a food chain. Most tertiary consumers like the cayote are omnivores.

Omnivores feed on both plants and animals. The cayote feeds not only on other animals like ducks, squirrels, fish, grasshoppers, but also feed on young plants and berries form plants.

The photo only shows us a cayote feeding on just one source of its diet which is a smaller animal. It cannot tell us that the cayote is not an omnivore because it doesn't show us the entire food web of the cayote in its ecosystem.

In conclusion, the cayote is a tertiary consumer. You cannot tell the cayote is not an omnivore from the photo.
