How do micro-organisms meet their needs?
Micro-organisms meet their needs by obtaining energy through various metabolic processes such as fermentation or respiration. They acquire nutrients essential for growth and reproduction by absorbing molecules from their environment. Micro-organisms also engage in activities like competition, cooperation, and adaptation to survive and thrive in their habitats.
What is the different between autotrophic and autotrophs?
Heterotrophic means obtaining ready made organic food from the environment and Autotrophic means manufacturing food from inorganic compounds usually carbon dioxide, water using a source of energy Autotrophic nutrition is a process where plants make food by combining large complex organic molecules such as starch, lipids and protein with simple inorganic molecules like water, carbon dioxide and minerals. Example: plants Hetrotrophic nutrition is where organism feed on organic substances that have been made by other organisms. Examples are animals and fungi

How are the words nutrient and nutrition related?
The word "nutrient" refers to a substance that provides nourishment, while "nutrition" is the process of obtaining and consuming nutrients to support growth and health in living organisms. Nutrients are the components of food that provide nourishment as part of the nutrition process.
Which organisms recycle the organic molecules of dead organisms at all trophic levels and return their nutrients to the environment?
Decomposers, such as bacteria, fungi, and detritivores like earthworms and maggots, work together to break down the organic molecules of dead organisms. By decomposing dead matter, they release nutrients back into the environment, completing the nutrient cycle.
Which organisms' manner of obtaining nutrition would be affected first?
Plantae:)
What is the the life activity by which organisms obtain and process food?
The life activity by which organisms obtain and process food is called nutrition. Organisms take in nutrients from their environment, break them down through various processes like digestion, and use the resulting molecules for energy, growth, and repair.
Which type of nutrition is believed to have come first?
Heterotrophic nutrition is believed to have come first in evolution. This type involves organisms obtaining organic compounds by consuming other living organisms or organic matter. Autotrophic nutrition, where organisms can produce their own food through photosynthesis or chemosynthesis, is thought to have evolved later.
What are the 2 uses of organic molecules in all organisms?
Organic molecules form the structure of all living organisms and derive energy from the organism's environment.
How do micro-organisms meet their needs?
Micro-organisms meet their needs by obtaining energy through various metabolic processes such as fermentation or respiration. They acquire nutrients essential for growth and reproduction by absorbing molecules from their environment. Micro-organisms also engage in activities like competition, cooperation, and adaptation to survive and thrive in their habitats.
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.
What is the different between autotrophic and autotrophs?
Heterotrophic means obtaining ready made organic food from the environment and Autotrophic means manufacturing food from inorganic compounds usually carbon dioxide, water using a source of energy Autotrophic nutrition is a process where plants make food by combining large complex organic molecules such as starch, lipids and protein with simple inorganic molecules like water, carbon dioxide and minerals. Example: plants Hetrotrophic nutrition is where organism feed on organic substances that have been made by other organisms. Examples are animals and fungi
What is the difference between nutrition and respiration?
Nutrition is the process by which organisms obtain and utilize nutrients for growth and energy. Respiration is the process of transferring energy from food molecules to ATP, which the cell uses for energy. While nutrition involves acquiring nutrients from the environment, respiration involves the internal process of breaking down these nutrients to release energy.
What are three of the life procsses that living organisms do?
Three life processes that living organisms do are obtaining and using energy, responding to the environment, and reproducing to ensure the survival of their species.
