Explanation:

For "Harmful algal bloom (HAB)"

• Textbook Definition: A harmful algal bloom (HAB) is a rapid growth of algae in aquatic environments that produces toxins or causes other negative impacts on ecosystems, wildlife, or human health.
• Definition in your own words: When algae grow too much in water (like oceans, lakes) and this growth is bad because it can make toxins, hurt animals, or cause problems for people.
• Written Example: Red tides (caused by dinoflagellates) are a type of HAB. In some coastal areas, red tides can kill fish and make shellfish unsafe to eat because of the toxins the algae produce.
• Image/Picture: You could include a picture of a coastal area with a reddish or greenish discoloration of the water (due to the algal bloom) or a microscopic image of the harmful algae.

For "Multicellular algae"

• Textbook Definition: Algae with bodies consisting of more than one cell.
• Definition in your own words: Algae that are made up of many cells (not just one), so they have a more complex structure than single - celled algae.
• Written Example: Kelp is a type of multicellular algae. Kelp forests in the ocean are made up of large, multicellular kelp plants that provide habitat for many marine organisms.
• Image/Picture: A picture of a kelp forest underwater, showing the long, leaf - like structures of the kelp, or a close - up of a multicellular green algae like Ulva (sea lettuce).

For "Autotroph"

• Textbook Definition: An organism that makes its own food by photosynthesis or chemosynthesis.
• Definition in your own words: A living thing that can make its own food instead of having to eat other things. Some do it using sunlight (photosynthesis, like plants and algae), and some use chemical reactions (chemosynthesis, like some bacteria in deep - sea vents).
• Written Example: A green plant is an autotroph. It uses sunlight, carbon dioxide, and water to make glucose (food) through photosynthesis. Another example is a chemosynthetic bacterium that lives near a deep - sea hydrothermal vent and makes food using the chemicals from the vent.
• Image/Picture: A picture of a green plant (showing photosynthesis in action, maybe with sunlight hitting the leaves) or a diagram of a deep - sea vent with chemosynthetic bacteria around it.
