K-7 Standard L.OL: Develop an understanding that plants and animals (including humans) have basic requirements for maintaining life which include the need for air, water and a source of energy. Understand that all life forms can be classified as producers, consumers, or decomposers as they are all part of a global food chain where food/energy is supplied by plants which need light to produce food/energy. Develop an understanding that plants and animals can be classified by observable traits and physical characteristics. Understand that all living organisms are composed of cells and they exhibit cell growth and division. Understand that all plants and animals have a definite life cycle, body parts, and systems to perform specific life functions. L.OL.E.5 Producers, Consumers, and Decomposers- All animals, including humans, are consumers that meet their energy by eating other organisms or their products. Consumers break down the structures of the organisms they eat to make the materials they need to grow and function. Decomposers, including bacteria and fungi, use dead organisms or their products to meet their energy needs.

	K-7 Standard L.EC: 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. Expectations   Vocabulary   Test Prep L.EC.06.11 List examples of populations, communities, and ecosystems including the Great Lakes region.   Species Ecosystem Habitat Adaptation Population Communities   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. Expectations   Vocabulary   Test Prep L.EC.06.21 Describe common patterns of relationships between and among populations (competition, parasitism, symbiosis, predator/prey).   Observe Evaluate Pattern Food web Predator Prey Ecosystem Population Competition Parasitism Symbiosis   L.EC.06.22 Explain how two populations of organisms can be mutually beneficial and how that can lead to interdependency.   Organism Ecosystem Beneficial Investigation Analyze Communicating Population Interdependency   L.EC.06.23 Predict how changes in one population might affect other populations based upon their relationships in the food web.   Observe Investigation Analyze Prediction Beneficial Detrimental Food web Population   L.EC.M.3 Biotic and Abiotic Factors- The number of 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. Expectations   Vocabulary   Test Prep L.EC.06.31 Identify the living (biotic) and nonliving (abiotic) components of an ecosystem.   Ecosystem Organism Living Non-living Biotic Abiotic   L.EC.06.32 Identify the factors in an ecosystem that influence changes in population size.   Evaluate Ecosystem Living Non-living Balance Population   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. Expectations   Vocabulary   Test Prep L.EC.06.41 Describe how human beings are part of the ecosystem of the Earth and that human activity can purposefully, or accidentally, alter the balance in ecosystems.   Evaluate Impact Ecosystem   L.EC.06.42 Predict possible consequences of overpopulation of organisms, including humans, (for example: species extinction, resource depletion, climate change, pollution).   Evaluate Prediction Impact Human population Ecosystem Positive Negative Over population Depletion Climate change Extinct Pollution Organism Species
