Study Notes
Understanding Living Things and Biodiversity
- Living things are distinguished from non-living things based on their ability to carry out seven vital functions necessary for maintaining life.
- The seven vital functions of living things include the need for food, oxygen, movement, growth, response to stimuli, excretion, and reproduction.
- Biodiversity encompasses a wide variety of living things, including animals, plants, and microorganisms, and is crucial for maintaining environmental balance and sustainability.
- Animals can be classified into vertebrates (with a backbone) and invertebrates (without a backbone), further categorized into fish, amphibians, reptiles, birds, and mammals.
- Plants can be classified into vascular (with vascular tissues) and non-vascular plants, further categorized into seed plants (producing seeds) and seedless plants.
- Human activities such as habitat destruction, overhunting, introduction of foreign species, and pollution pose threats to the survival of living things and lead to a rapid reduction in biodiversity.
- Conservation is essential for maintaining biodiversity, and individuals can contribute by not disturbing wild animals and plants, avoiding littering, and participating in conservation programs.
- The 4Rs principle (Reduce, Reuse, Recycle, and Recover) can help reduce pollution and maintain biodiversity.
- Reduce involves reducing the use of resources.
- Reuse involves reusing resources rather than discarding them.
- Recycle involves recycling materials to make new products.
- Recover involves replacing environmentally harmful materials with less harmful ones.
