Study Notes
Adaptations
- Organisms have specific features that allow them to survive in their natural habitat.
- Camels have long legs, excrete small amounts of urine, have dry dung, and don't sweat, enabling them to survive in deserts.
- Fish have streamlined bodies, slippery scales, flat fins, and tails, allowing them to move easily underwater.
- Adaptations are crucial for survival, as organisms that cannot adapt to changes in their environment may die.
Habitats
- The place where organisms live is called a habitat, which provides food, water, air, shelter, and other necessities.
- Terrestrial habitats include deserts, forests, and mountains.
- Aquatic habitats include oceans, ponds, lakes, and rivers.
Abiotic Factors
- Abiotic components of a habitat include non-living things like rocks, soil, air, and water.
- Sunlight and heat are also abiotic factors.
- Abiotic factors play a vital role in the growth of plants and survival of all living organisms.
Plants and Water
- Some plants grow in water and have adapted to survive in these conditions.
- Aquatic plants have reduced roots, long hollow stems, and leaves that float on the surface.
- Submerged plants have narrow and thin ribbon-like leaves that bend in the flowing water, preventing damage.
Life Processes: Growth, Reproduction, and Excretion
- All living organisms require food for growth and energy.
- Plants make their own food through photosynthesis, while animals depend on plants or other animals for food.
- Growth is a characteristic of all living things.
- Plants and animals can reproduce and create offspring, ensuring the continuation of their species.
- Living organisms excrete waste products.
- Different types of plants and animals utilize various mechanisms for excretion.
Responsiveness to Stimuli
- Living organisms respond to changes in their environment.
- Plants can bend towards light, a response to a stimulus.
