Aquatic Biomes

During a school field trip to a local nature reserve, students are learning about different ecosystems. The guide asks, 'What are the main types of freshwater biomes?'

• Oceans and seas

• Mountains and valleys

• Deserts and tundras

• Rivers and streams, lakes and ponds, and wetlands

Name the largest marine biome on Earth.

• Freshwater biome

• Desert biome

• Tundra biome

• Oceanic biome

What are estuaries and why are they important?

• Estuaries are important because they serve as nurseries for many marine species, provide habitat for wildlife, and act as filters for pollutants.

• Estuaries are important because they are dry land with no water

• Estuaries are important because they are home to desert species

• Estuaries are important because they have no impact on marine life

Explain the significance of coral reefs in the aquatic ecosystem.

• Coral reefs provide habitat for marine life, protect coastlines, and support local economies.

• Coral reefs are harmful to marine life

• Coral reefs have no impact on the aquatic ecosystem

• Coral reefs are only important for tourism

Imagine visiting the Florida Everglades, a vast network of wetlands. What role do these wetlands play in the environment?

• Wetlands have no impact on the environment

• Wetlands are dry areas with no water present

• Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year. Their role in the environment includes providing habitat for a diverse range of plant and animal species, acting as a natural filter for water, and helping to control flooding.

• Wetlands are only home to a few species and do not contribute to biodiversity

Imagine you are a biologist studying a rocky shoreline. Describe the characteristics of the intertidal zone you are observing.

• Constantly changing environmental conditions

• Stable and unchanging environmental conditions

• No impact from tides

• Limited biodiversity

During a school field trip to a national park, students are asked to identify different types of biomes they observe. Which of the following would be considered examples of freshwater biomes?

• Deserts and tundras

• Mountains and forests

• Lakes, rivers, ponds, and wetlands

• Oceans and seas

How do marine biomes differ from freshwater biomes?

• Tropical vs. temperate

• Shallow vs. deep

• Polluted vs. clean

• Saltwater vs. freshwater

What are the threats to the Great Barrier Reef and how can it be protected?

• Promoting unsustainable fishing practices

• Destroying marine protected areas

• Reducing carbon emissions, creating marine protected areas, and promoting sustainable fishing practices

• Increasing carbon emissions and pollution

Why are estuaries considered as nurseries for many marine species?

• Estuaries are too shallow and do not provide enough shelter for young marine species.

• Estuaries have a very high salinity level, which is harmful to the growth of young marine species.

• Estuaries provide a mix of fresh and saltwater, abundant nutrients, and shelter, making them ideal for the growth and protection of young marine species.

• Estuaries have very low levels of nutrients, making them unsuitable for the growth of young marine species.
