please give 2-3 examples (for each one) of producers, primary consumers, secondary consumers, tertiary consumers, and quaternary
Elis [28]
Producers:

One example of producers found in food chains include plants. They use photosynthesis to make their own food. Examples of plants include trees, grass, moss, flowers, and weeds, to name a few.

Primary consumers are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).

Types of Secondary Consumers
Spiders, snakes, and seals are all examples of carnivorous secondary consumers. Omnivores are the other type of secondary consumer. They eat both plant and animal materials for energy. Bears and skunks are examples of omnivorous secondary consumers that both hunt prey and eat plants.


In the real world, a tertiary consumer can eat many different animals and even plants sometimes. This means that they can actually be carnivorous or omnivorous. Some examples of tertiary consumers include, birds of prey, big cats, and foxes.

Alyssa investigates properties of matter. The answer to which question would best
timofeeve [1]

Answer:

This question is incomplete as it lacks options, the options are:

A) What is the radius of each particle of the substance?

B) Does the substance contain more than one type of atom?

C) Was a chemical reaction necessary to create the substance?

D) What is the electrical charge of the particles of the substance?

The answer is B

Explanation:

In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.

According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?

- If the answer is yes, the substance is a COMPOUND

- If the answer is no, the substance is an ELEMENT.
