SNC2LW Ecology Research Notes Biology Unit Label each level organization on the diagram below. biosphere – thin layer of earth and it’s atmosphere that supports life (air, land, water). community – many interdependent species living in the same area. ecosystem – the interaction of living and non-living things in an area. organism – a living individual population – all the members of a single species interbreeding & competing for resources in the same area. An ecosystem consists of both biotic (living) and abiotic (non-living) things interacting together in a natural environment. Sort the biotic and abiotic limiting factors to population size in a community. Biotic (living) Abiotic (non-living) Describe the 4 basic needs of all living organisms. 1. 2. 3. 4. What are some things that you could do without and still have all of your basic needs met? ____________________________________________________ ___________________________________________________________ ____________________________________________________ ___________________________________________________________ ____________________________________________________ ___________________________________________________________ _____________________________________________________ ___________________________________________________________ An adaptation is an inherited or learned characteristic that helps an organism survive and reproduce in its environment. There are two different types of adaptations: behavioral and structural. Sample adaptation by organisim to environment How the adaptation enables the organisim to survive Behavioral Adaptations Structural Adaptations Producers can make their own food and supply the matter and energy they need for survival. Illustrate the food-making process of photosynthesis carried out by producers. Consumers eat producers and other consumers: Herbivores – eats plants Carnivores – eats meat Omnivores – eats both meat and plants A food web is a combination of many different food chains, showing the interrelationships between and among many different producers and consumers in an ecosystem. Illustrate these interrelationships in a food web that includes your food chain, above. Energy flow is the movement of the sun’s energy from one organism to another. llustrate the flow of energy in a food chain from producer to primary consumer, to secondary consumer, to tertiary consumer, to scavenger, to decomposer. An ecological food pyramid is a model that represents the number of organisims consumed at each successive level of the food chain. The size of each level indicates the number of organisims at that level. Illustrate
