All of them since they are organic. Lipids, proteins, carbohydrates and nucleic acids are considered to be the 4 groups of biological macromolecules.

Animals obtain their energy and carbon from?

Animals obtain their energy and carbon from consuming other living organisms, such as plants or other animals. They break down these organic molecules through digestion to extract the energy and carbon they need for their own growth, metabolism, and reproduction.


Is a animal cell a saprotroph or heterotroph or autotroph?

Animals are heterotrophic organisms. They obtain carbon from other animals.


Why is there no chloroplasts in animal cells?

Animals are chemoheterotrophic organisms. They obtain energy and carbon through other organisms.


How does chemoheterotrophs obtain carbon?

Chemoheterotrophs obtain carbon by consuming organic compounds from their environment. They cannot produce their own food through photosynthesis and depend on other organisms for a source of carbon. This carbon is used in their metabolism to generate energy and build cellular components.


Where does carbon come from in an ecosystem?

Carbon in an ecosystem primarily comes from the atmosphere in the form of carbon dioxide. Plants absorb carbon dioxide during photosynthesis and incorporate carbon into their tissues. When organisms consume plants or other organisms, they obtain carbon for growth and metabolism. Carbon is cycled through the ecosystem as organisms respire, decompose, and are consumed by other organisms.


What organisms that require organic sources of carbon and energy?

Heterotrophic organisms, such as animals, fungi, and many bacteria, require organic sources of carbon and energy for their growth and metabolism. These organisms cannot produce their own food and must obtain it from other living or dead organic material.


How do nonphotosynthetic organisms obtain the carbon molecules necessary for life?

From dead and decay matter.


What is the source from which organisms generally take elements is called?

The source from which organisms generally take elements is called the environment. Organisms obtain essential elements such as carbon, hydrogen, oxygen, nitrogen, and phosphorus from air, water, soil, and other living organisms in their environment.


Is carbon passed along the food chain?

Yes, carbon is passed along the food chain as organisms consume other organisms. When organisms eat, they obtain carbon-containing molecules from their food, which are used for energy and growth. When these organisms are consumed by others, the carbon is further passed along the food chain.


In an ecosystem what happens to the atoms of certain chemical elements such as carbon oxygen and nitrogen?

In an ecosystem, atoms of elements such as carbon, oxygen, and nitrogen are continuously cycled between living organisms and the environment. Producers like plants take in carbon dioxide and nitrogen from the air and water, while consumers obtain these elements by consuming other organisms. Decomposers break down organic matter, returning these atoms to the environment for reuse by other organisms.


How do plants obtain carbon?

Plants obtain carbon dioxide from the air through tiny pores in their leaves called stomata. This carbon dioxide is used in photosynthesis to produce glucose, which serves as a source of energy for the plant.


Why are chloroplast not needed in an animal cell?

Animals are heterotropic organisms.They obtain carbon from other organisms.
