Algae
Algae are a diverse group of photosynthetic organisms that are found in various environments, including freshwater, marine, and even some extreme environments like hot springs and snow. They play a crucial role in the ecosystem as they are the primary producers, providing food and oxygen for other organisms.
Types of Algae
There are various types of algae including:
- Green Algae: Found in freshwater, marine, and terrestrial environments.
- Brown Algae: Predominantly found in marine environments, such as kelp forests.
- Red Algae: Primarily found in marine environments and are often used in food products such as agar and nori.
- Blue-Green Algae (Cyanobacteria): Often found in freshwater and are capable of nitrogen fixation.
Importance of Algae
Algae are essential for various reasons:
- They are the base of the aquatic food web, providing food for a wide range of organisms.
- They produce a significant amount of the world's oxygen through photosynthesis.
- Some species of algae are used as food for humans and animals.
- Algae are also being studied for their potential in biofuel production.

The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
Biodiversity: Students compare living things based on their behaviors, external features, and environmental needs.
Describe how living things can be sorted in many ways, depending on which features or behaviors are used to sort them, and apply this understanding to sort living things.
