Study Notes
Crocodile Habitat
- Crocodiles are found in tropical climates across Africa, Australia, Asia, Central, and North America.
- They require a tropical environment with water (including salty water) and safe places to lay eggs.
Tropical Climates
- Crocodiles live in warm temperatures, typical of tropical climates, which are perfect for them.
- They thrive in jungles, marshes, and other warm and humid environments.
Salty Water
- Crocodiles can live in brackish water, which is a mix of fresh and saltwater.
- This unique ability allows them to inhabit areas other reptiles can't, like mangrove swamps and the Florida Everglades.
Places to Lay Eggs
- Crocodiles lay eggs in holes buried in the sand near water.
- They choose nesting spots carefully to avoid wet, hot, or cold conditions and predators.
Crocodiles in Danger
- Human development and deforestation have pushed some crocodile species out of their habitats, making them harder to find.
- Humans encroaching on tropical and swampy habitats has led to a decline in crocodile populations.
Plant Structure and Function
- Plants have three main parts: the crown, trunk, and roots.
- The trunk has five layers: bark, cambium, heartwood, phloem, and xylem.
Plant Types
- Angiosperms (like daisies) have flowers, while gymnosperms (like pine trees) do not.
- Plants without flowers include mosses and ferns that reproduce with spores.
Parts of a Plant
- Roots hold the plant in place, absorb water and nutrients, and store food.
- Stems support leaves, flowers, or fruit, and carry water and nutrients from roots to the rest of the plant.
- Leaves make food through photosynthesis, using sunlight, carbon dioxide, and water, and give off oxygen.
Leaves and Photosynthesis
- Leaves need sunlight, carbon dioxide, and water to perform photosynthesis.
- During photosynthesis, plants produce a sugar for energy and release oxygen.
Flowers and Fruit
- Flowers attract insects or animals for pollination, providing nectar in return.
- Some flowers turn into fruit, which allows plants to spread seeds and reproduce.
Seeds and Dispersal
- Seeds can travel through wind, water, or animals, allowing plants to spread and grow in new areas.
