Wetlands

• Transitional zones between land and water• Many different species • Swamps, marshes, bogs

Swamp

Marsh

Bog

Mangrove

Soil

• Often saturated long enough to become anaerobic (no oxygen)

• Wetland vegetation must be able to tolerate both flooding and the lack of oxygen in the soil.

Two Types of Wetlands

Inland and coastal. • Inland wetlands are freshwater ecosystems

and include marshes, swamps, riverine wetlands, and bogs.

• Coastal wetlands may be either fresh or salt water and are affected by tides.

• Examples include tidal salt marshes, tidal freshwater marshes, and mangroves.

Observation vs Inference

• Observation is the process of gathering information using the five senses (sight, smell, etc.).

• Inference is the ability to use observations to make informed decisions.

• For example, a group of students working on the Wetlands... inquiry observe that the red-tailed hawk is larger than most birds, has a hooked beak, and sharp claws.

• They infer that the hawk is a carnivore based on these observations and consequently place the hawk at the top of several food chains they are brainstorming in their group.

Food Chains/webs

• A food chain shows the connections between individual organisms that depend on each other for energy.

• A food web shows all of the energy connections among living things within a community or ecosystem.
