1. Darwin found that various finches descended from a common ancestor. This is an example of ___ Examples of Natural Selection Asexual ReproductionOrganisms capable of making food from sunlight An organism capable of producing its own food The theory of Natural Selection was proposed by ____ An animal that feeds on another animal. Ex. Lion A group of similar organisms that can breed (reproduce/sex) and have fertile offspring All the members of the same species that live in one area. An organism that feeds on plants. Ex. rabbit A group of organisms and the nonliving components of an environment. The differences between prokaryote and eukaryote. A bacterium is also known as a ______ Different populations of organisms interacting in a shared environment The sum of all chemical changes taking place in an organism An animal that eats both plants and animals. Ex. people

2. ProkaryoteCommunity Prokaryote has no nucleus, circular chromosome and small ribosomes. Eukaryote has membrane bound organelles, nucleus, linear chromosomes, and more complex. Metabolism Producer The formation of new individuals from a single parent.

3. The elements found in all living things All living things are composed of at least 1 _____ A group of cells performing a job or function. The primary source of all energy A part within a cell with a job. Ex. Ribosome and mitochondria A group of tissues working together to perform a job. A group of organs working together to perform a job. The form of energy cells use to do work. The ability to keep the internal environment stable. Ex. Keep blood sugar within a certain range or body temperature The portion of the Earth occupied by living organisms, including the atmosphere, land and bodies of water. A series of orderly changes (phases) by which an organism comes into existence. Ex. Caterpillar to moth Digestion, synthesis, making and breaking bonds are all part of this characteristic of life. Reacting to irritants is this characteristic of life. Ex. Move toward food or away from a toxin List the 8 characteristics of living things Characteristic of life NOT required for an individual organism to live. The process by which cells produce energy in the form of ATP and release CO2 as a waste product.
