Ecology Vocab What is Ecology? Ecology- The relationship between organisms and its environment. It is made up of an ecosystem that contains communities consisting of biotic and abiotic factors that make up populations within that ecosystem. Population- all the members of one species in an area Community- a group of plants and animals living and interacting together with one another in a specific area. Ecosystem- all the members of a community plus the abiotic factors influencing one another Biotic- an organism that is living or was once living Abiotic- nonliving factors of an environment Organism- any individual living thing, whether it is a plant or animal Climax Community- a community of plants and animals that reach a stable equilibrium Biomes- Global habitats determined by temperature and rainfall. -based on types of plants -they have specific characteristics Ecotones- the overlapping of boundaries and blending of different biomes Biomes 1. Tundra Treeless biome that is covered by a surface soil, underneath it is frozen. Plants and animals that live here must be adapted to cold temperatures, little vegetation grows here. 2. Temperate Deciduous Forest Warm winters and long summers Trees lose their leaves and change colors Rich soil and lots of vegetation 3. Desert Dry and very hot during the day, can become very cold at night Less than 25cm of rain per year Plants and animals must conserve water 4. Savanna Tropical or subtropical grasslands with scattered trees or shrubs Plants and animals must deal with drought (Lion King) 5. Taiga Forested area which contains conebearing evergreens (pines and spruce) Plants and animals must adapt to cold long winters 6. Temperate Grasslands Mostly grass with little rainfall, which doesn’t allow for many trees to grow Soil is rich and is always producing vegetation 7. Tropical Rainforest Stable year round growing and abudent rainfall Trees form a canopy that shades the forest floor Largest species richness of all biomes Life Zone- a way to describe an area that has similar plant and animal communities. Biotic Community -a group of interdependent organisms in the same habitat interacting with one another. Climate -the “average’ weather Herbivore -an organism that eats only plants Carnivore -an organism who eats mostly meats Omnivore -an organism who eats meat and plants equally Decomposer -breaks down dead and decaying plants and animals Food Web- shows how plants and animals are connected in many different ways Trophic Level-position in the food chain determined by the energy transfer of that organism Food Chain-shows how plants and animals are connected by a linear (single) pathway. Producers- plants that provide food for herbivores, carnivores, and omnivores Primary Consumer- 2nd trophic level that is made up of herbivores and bacteria/fungi. Secondary Consumers- 3rd trophic level that is made up of secondary carnivores and omnivores Tertiary Consumers- 4th trophic level that is made up of primary carnivores (larger animals)
