Study Notes
Ecosystems
- An ecosystem is composed of living organisms and their environment.
- It consists of both biotic (living) and abiotic (non-living) components.
Biotic Components
- Examples of biotic components include plants, animals, and microorganisms.
Importance of Water
- Water is essential for living things to survive.
Energy Sources
- Living things get energy from various sources, including the sun, food, and chemical reactions.
Symbiosis
- Mutualism is a type of symbiosis where both organisms benefit from each other.
- An example of mutualism is the relationship between ants and aphids.
- Other types of symbiosis include parasitism, commensalism, and predation.
Adaptation
- Adaptation is how organisms respond to their environment.
- It is a key feature of evolution and allows organisms to survive and thrive in different conditions.
Living Conditions
- Different types of organisms can live in various conditions, such as extreme temperatures, high salinity, and low oxygen levels.
True or False Statements
- True: All living things need water, food, and energy to survive.
- False: All living things need oxygen to provide the energy they need to survive.
- True: Symbiosis is a relationship between two different organisms where each partner benefits from the relationship (in the case of mutualism).
- True: Predation occurs when members of one species eat members of another species.
- True: Adaptation is how organisms respond to their environment.
