- climax community
- a A combination of plant and animal forms that dominate mature ecological communities. Climax communities are unique and shaped by various factors, including temperature, rainfall, and soil acidity.
- b A firm but flexible substance, found in regions of vertebrate skeletons, such as the ribs, that need to bend.
- c The unique role a population plays in a community. A niche includes all characteristics that define the way a population exists in a community, from where the members live to what they eat, when they sleep, and how they reproduce.
- d An evolutionary theory (proved false by Darwin) stating that species change over time by the use and disuse of structures and the inheritance of acquired traits.
- e A particular geographic area with a common climate and characteristic plant and animal life. There are six major terrestrial biomes and two aquatic biomes. The six terrestrial biomes are tropical rain forest, savanna, desert, temperate deciduous forest, taiga, and tundra. The two aquatic biomes are marine and freshwater. Each biome is characterized by specific climax communities.

- Slender horizontal stem that can form new plants via specialized nodes.
- The involuntary half of the peripheral nervous system. The autonomic nervous system is in two antagonistic parts: the sympathetic and parasympathetic nervous systems. Their interactions control smooth and cardiac muscle, glands, and organs and processes such as heartbeat, the movements of the digestive tract, and the contraction of the bladder.
- A type of white blood cell that kills invading cells by ingesting them.
- A trait that is morphologically and functionally similar to that of a different species but that arose from a distinct, ancestral condition.
- The medium depth zone of the marine biome. Extends to 600 feet beneath the water's surface and sits on the continental shelf, hundreds of miles from any shore. Algae, crustaceans, and fish inhabit this region.
5 True/False questions
photosynthesis → The process by which plants and other autotrophic organisms convert light energy into organic materials, such as glucose.
style → Vascular tissue composed of cells that are dead at maturity; transports water and dissolved minerals upward from the roots to the shoot.
hypothalamus → A situation in which the concentration of solutes in a solution is lower than what an organism contains. An example is a paramecium in pond water: the organism has more solutes than its environment, so water flows into the cell by osmosis. Paramecia have evolved contractile vacuoles to keep from exploding.
heredity → The genetic transmission of traits from parents to offspring, so that offspring resemble their parents. Traits transmitted this way are called hereditary traits.
warm-blooded → Animals that have developed fat and fur, hair, or feathers in order to retain heat produced by metabolic activities. Also known as endothermic. Warm-blooded animals are able to thrive in various climates, because they are minimally affected by environmental fluctuations in temperature.
