K-7 STANDARD L.EC: ECOSYSTEMS Develop an understanding of the interdependence of the variety of populations, communities and ecosystems, including those in the Great Lakes region. Develop an understanding of different types of interdependence and that biotic (living) and abiotic (non-living) factors affect the balance of an ecosystem. Understand that all organisms cause changes, some detrimental and others beneficial, in the environment where they live.
L.EC.M.1 Interactions of Organisms - Organisms of one species form a population. Populations of different organisms interact and form communities. Living communities and nonliving factors that interact with them form ecosystems.	Amphibians and Reptiles - This event will test knowledge of amphibians, turtles, crocodiles, and reptiles. Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes.
L.EC.M.2 Relationships of Organisms - Two types of organisms may interact with one another in several ways: They may be in a producer/consumer, predator/prey, or parasite/host relationship. Some organisms may scavenge or decompose another. Relationships may be competitive or mutually beneficial. Some species have become so adapted to each other that neither could survive without the other.	Disease Detectives - Students will use their investigative skills in the scientific study of disease, injury, health, and disability in populations or groups of people. There will be a focus on environmental causes of public health problems. Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes.
L.EC.M.3 Biotic and Abiotic Factors - The number or organisms and populations an ecosystem can support depends on the biotic (living) resources available and abiotic (nonliving) factors, such as quality of light and water, range of temperatures and soil composition.	Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes.
L.EC.M.4 Environmental Impact of Organisms - All organisms (including humans) cause change in the environment where they live. Some of the changes are harmful to the organism or other organisms, whereas others are helpful.	Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes.
