Answers

Answer 1

Answer:

heterotroph type of organism is at the lowest level of the food chain. Thus, the correct option is D.

What is heterotroph?

A heterotroph is defined as an organism which eats other plants or animals for energy and nutrients.

Heterotrophs positioned at the second and third levels in a food chain from the lowest, a sequence of organisms which provide energy and nutrients for other organisms. Each food chain comprised of three trophic levels, that describe an role of organism in an ecosystem.

Answer 2

Answer:

Answer:

heterotroph

Explanation:

A heterotroph is an organism that cannot fix carbon and uses organic carbon for growth. Heterotrophs can be further divided based on how they obtain energy; if the heterotroph uses light for energy, then it is considered a photoheterotroph, while if the heterotroph uses chemical energy, it is considered a chemoheterotroph.

Nelly was reading about ecological pesticides. She found a website that said that skeletons of some organisms settle as sediments in the ocean. They are then used as pesticides because they are abrasive against pests. Which organism is the article discussing?A. dinoflagellates
B. diatoms
C. green algae
D. euglenoids
E. amoeba

Answers

The answer is B. When diatoms die and fall off the ocean column to the ocean floor, they become part of sediments over time. When they are mined and exposed, they turn to a diatomite. Diatomaceous earth is significant as a pest repellant because of its hygroscopic property and has very abrasive particle hence it absorbs the water-protective fats and oils from the outermost layer of insects.

Answer:

B. diatoms

you are a molecule of carbon. choose a starting point in the carbon cycle and describe the process you would go through to move through the entire cycle

Answers

The carbon cycle is a natural way to recycle carbon in the environment. It usually starts with the atmosphere and ends by getting released into the atmosphere itself.

What are the steps of carbon cycle?

The carbon released into the atmosphere through either respiration, combustion of fossil fuels, vehicles, etc.

The main steps involved in carbon cycle are:

Carbon moves to plants through atmosphere.
From plants it goes to animals.
When plants and animals die, the carbon is then released to the soil.
Carbon also released from the fossil fuels on burning.
It also comes from oceans to the atmosphere.

Thus, it can be concluded that the molecule of carbon starts from atmosphere and ends by being released to the atmosphere.

What happens to the kinetic energy of a snowball as it rolls across the lawn and gains mass.

Answers

Kinetic energy of a snowball will increase as it rolls across the lawn and gains mass. We already know that Kinetic energy is directly proportional to speed. We can express kinetic energy by the formula
Kinetic energy = 1/2 mv^2
Now as the mass increases and the velocity remains constant, the kinetic energy of the snowball is bound to increase. I hope the explanation has helped you.

Answer:

Kinetic Energy Increases

Why is the term unique appropriate to describe unicellular organisms

Answers

Answer:

Unicellular organisms are composed of a single cell, unlike multicellular organisms that are made of many cells. This means that they each live and carry out all of their life processes as one single cell.

Explanation:

Final answer:

Unicellular organisms are unique because they are single-celled organisms, able to carry out all necessary life processes within a single cell, unlike multicellular organisms that have distinct cells for various functions.

Explanation:

The term unique is appropriate to describe unicellular organisms because these living entities are single-celled organisms. Unique here means there is a distinctive feature about these organisms, which is, they exist as a single cell, unlike multicellular organisms that are made up of many cells. Examples of unicellular organisms include bacteria, yeast, and some protozoans.

The distinctiveness of unicellular organisms also lies in their ability to carry out all necessary life processes like nutrition, respiration, excretion, growth, reproduction, and response to stimuli within their singular cell. In contrast, multicellular organisms have an organ system where dedicated cells carry out these functions. Therefore, the simplicity and functionality of unicellular organisms make them quite unique.
