Study Notes
Environment Overview
- Environment consists of living (plants, animals) and non-living (water, soil) components.
- Animals use sensory parts such as eyes, ears, and nose to locate food.
- Movement in animals is aided by body parts like legs, fins, and wings.
Ocean Environment
- Oceans are vast bodies of salty water, characterized by their depth and temperature variations.
- Most marine animals thrive near the surface where food and warmth are abundant.
- Plants in the ocean, like algae, predominantly live near the surface to access sunlight for photosynthesis.
- Algae serves as a primary food source for many sea creatures, including crabs and fish.
Example of Ocean Life: Seahorse
- Seahorses possess gills, enabling them to extract oxygen from water.
- Fins are essential for their movement and navigation in aquatic environments.
- They can change color as a defense mechanism to evade predators.
Marsh Environment
- Marshes are wetlands, regions where land is frequently covered with water, providing unique habitats.
- Wetlands play a critical role in supporting biodiversity and water filtration.
- Water lilies are a common plant found in marshes, featuring adaptations for their aquatic habitat.
Water Lily Adaptations
- Roots absorb nutrients from the waterlogged soil, vital for growth.
- Long stems elevate leaves, allowing for improved access to light and air.
Example of Marsh Life: Great Egret
- The great egret has a sharp, elongated beak adapted for catching fish and other food sources.
- Long legs allow the egret to stand in deep water, facilitating hunting in marshy environments.
