Study Notes
Biodiversity and Biology
- Biodiversity refers to the great variety of life on Earth, with an estimated 8.7 million plant and animal types believed to be on the planet.
- Biology is the study of life and living organisms, and is significant because it helps us understand how to maintain and preserve life on Earth.
Energy and Ecosystems
- The main source of all energy on earth is the sun.
- In an ecosystem, chemical cycling and energy flow begin when plants use solar energy and inorganic nutrients to produce their own food through the process of photosynthesis.
- Energy is passed from one population to another in a food chain through the process of energy flow.
Organisms and Environment
- The ability of an organism to maintain its internal environment stable despite changes in the external environment is called homeostasis.
- The ability to recognize that something in an organism's surroundings has changed and respond to it quickly is called a response to stimuli.
- The phenotypic response to an environmental change is called adaptation.
- Unicellular organisms, such as bacteria, differ from multicellular organisms like humans in that they consist of a single cell.
- Plants called succulents adapt to life in dry, hot deserts by storing water in their leaves and stems.
Genetics and Evolution
- The genetic material that encodes an organism's structures and functions is DNA.
- Genetic changes in a population over time producing a new population is called evolution.
- The basic unit of life is the cell.
- Organisms made up of more than one cell are called multicellular organisms.
Photosynthesis and Energy
- Photosynthesis is the process by which some organisms capture solar energy from the sun and transform it into chemical energy.
- Plants use solar energy and inorganic nutrients to produce their own food through photosynthesis.
