Which group of organisms does not depend upon obtaining preformed organic molecules from the environment for nutrition?

Autotrophs do not depend on obtaining preformed organic molecules from the environment for nutrition. They are capable of producing their own food through processes like photosynthesis or chemosynthesis. Examples include plants, algae, and some bacteria.


What do you call an organism that consumes pre-existing organic molecules?

Organisms that consume preexisting organic molecules are called heterotrophs.


What do autotrophs make that heterotrophs need?

Autotrophs don't necessarily "make" anything that heterotrophs need. The word autotroph means that the organism produces its own source of food. Heterotrophs depend on autotrophs as an essential source of food and nutrients (nitrogen, etc.).


What are organism that must take in organic molecules for both energy and a supply of carbon?

Organisms that must take in organic molecules for both energy and a supply of carbon are known as heterotrophs. This group includes animals, fungi, and many bacteria and protists. Heterotrophs rely on consuming other organisms or organic matter to obtain the necessary nutrients and energy for their growth and metabolism. In contrast, autotrophs can produce their own organic molecules using inorganic sources, such as sunlight or carbon dioxide.


Why Heterotrophs are dependent on autotrophs.?

Heterotrophs are dependent on autotrophs for a variety of reasons. The most obvious reason is that autotrophs are the only organisms that can produce organic molecules from inorganic molecules. This means that heterotrophs must consume autotrophs (or the organic molecules they produce) in order to obtain the organic molecules they need to survive. In addition to this, autotrophs play a vital role in the global carbon and water cycles. They take in carbon dioxide from the atmosphere and use it to produce organic molecules. This helps to remove carbon dioxide from the atmosphere, which would otherwise contribute to global warming. Autotrophs also release water vapor into the atmosphere through the process of transpiration. This helps to regulate the Earth's temperature and keep it habitable for other organisms. Without autotrophs, the world would be a very different place. Heterotrophs would not be able to survive, and the planet would be uninhabitable for most other organisms.

Are fungi autotrphs?

No, fungi are not autotrophs. They are heterotrophs, meaning they obtain their nutrients by absorbing organic matter from their environment.


What is the organisms that break down dead organic matter in order to absorb the nutrient molecules?

heterotrophs


Which type of organism obtains energy by metabolizing organic molecules produced by other organisms?

Heterotrophs


What are heterotrophs and where do they get their energy?

Heterotrophs are organisms that cannot produce their own food and must consume organic matter from other organisms to obtain energy. They get their energy by breaking down complex organic molecules, such as carbohydrates, proteins, and fats, through processes like digestion and cellular respiration.


How do heterotrophs get carbon molecules?

Heterotrophs obtain carbon molecules by consuming other organisms or organic matter. They break down the complex organic molecules into simpler forms through processes like digestion and cellular respiration to obtain the carbon they need for growth and energy production.


Autotrophs and heterotrophs use carbon containing molecules for energy and for?

Autotrophs use carbon-containing molecules for energy and to build organic compounds through photosynthesis. Heterotrophs obtain these carbon-containing molecules by consuming other organisms or their organic matter for energy and to support their own growth and metabolism.


What do fungi secrete to digest food?

Fungi use extracellular digestion. They must obtain preformed organic molecules (nutrients) from the environment. The fungus will secrete enzymes to hydrolyze complexes into simpler molecules - which are then absorbed. Once inside, the simpler molecules can be used for energy or to synthesize larger molecules.

Heterotrophs get carbon molecules by?

Heterotrophs get carbon molecules by consuming other organisms or their byproducts through processes such as feeding and digestion. They rely on autotrophs to synthesize organic compounds that contain carbon through photosynthesis or chemosynthesis.


Are fungi autotrophic?

No, fungi are not autotrophic. They are heterotrophic organisms, meaning they obtain nutrients by breaking down organic matter in their environment. Fungi secrete enzymes to break down complex organic molecules into simpler forms that they can then absorb for nutrition.
