What are the levels of organization in an organism?
- Cell
- Tissue
- Organ
- Organ System
These levels represent the structural hierarchy within biological organisms.
Define nutrition in the context of organisms.
The process by which the energy and materials are obtained for the maintenance of life
Nutrition is essential for growth and survival.
What is the process by which green plants produce their own food?
Photosynthesis
This process uses solar energy to convert carbon dioxide and water into glucose and oxygen.
What are the two types of autotrophs?
- Photo-autotrophs
- Chemo-autotrophs
Autotrophs produce their own food using different energy sources.
What do photo-autotrophs use to produce their own food?
Solar energy
They convert solar energy into chemical energy through photosynthesis.
What do chemo-autotrophs use to produce their own food?
Chemical energy
They obtain energy from chemical reactions to synthesize their food.
Give an example of a chemo-autotroph.
Some bacteria
These organisms can produce their own food using chemical energy.
What are heterotrophic organisms?
Organisms that cannot produce food by themselves and depend on others
Examples include animals that rely on consuming other organisms for energy.
