1. Organisms interactions

2. Carl Linnaeus is the father of Science Nomenclature: The system used for classifying organisms. In the plant and animal kingdoms organisms are arranged into: Domain Kingdom Phylum Class Order Family Genus Species

3. Science Nomenclature

4. The 5 Kingdoms 1.Animalia: Animals 2.Plantae: Plants 3.Fungi: Mushrooms, mold 4.Monera: Monerans include all bacteria. They are composed of prokaryotic cells. This means they are all one celled organisms, and have the ability to move around and have cell walls. 5.Protista: relatively simple organization (unicellular, one celled)

5. Organisms Life Needs Food, water, air, shelter, energy and space are the life needs of organisms. Growth, reproduction, energy transformations, respiration, waste removal, movement and responses are basic life processes. They all depend on energy transformations.

6. Plant Life Needs The life needs of plants are: light, energy source, gases, water, and nutrients. Chlorophyll is a chemical in chloroplasts that can absorb or trap energy and transform it into chemical energy called glucose Plants respond to light by growing toward it or away form it (phototropism)

7. Populations Organisms exist as a member of their population. They interact by competing for basic resources, mates, and territory Populations cooperate with each other to meet needs and have social order to ensure that labor and resources are shared Independent behavior and group behavior can influence a population

8. Interactions Every organism fills a specific niche, or role in its community 1.Producers (Plants) are photosynthesizers that are the beginning of food chains 2.Predators are animals that kill and eat other animals. 3.Prey are animals that are hunted by other animals for food. 4.Omnivores are animals that eat animals and plants. 5.Heterotroph’s are consumers, an organism that must obtain their food from eating other organisms.

9. Predator Prey Relationships

10. Interactions continued 6. Herbivores are animals that eat only plants. 7. Carnivores are animals that eat only meat. 8. Scavengers feed off dead animals. 9. Decomposers are organisms that break down other organisms. (bacteria, fungi)

11. Types of Symbiotic Relationships 1.Mutualisms when both organisms benefit (Sea anemone and clown fish) 2.Commensalisms is when one organism benefits and the other is unaffected (cleaner shrimp and Nemo) 3.Parasitism is when one organism benefits and the other is harmed (Tape-Worm)

12. Food Chains A food chain is a diagram of relationships between living organisms. Shows living things depend on other things to live. Animals eat other animals to survive. A complex balance of life. If one animal source of food disappears, other animals may be impacted and die. A food web is two or more food chains hooked together. A food pyramid shows relative amounts of energy available to each level.

13. Food Chains & Webs

14. Predator, Prey and the Food Chain

15. Levels 1st level consumer- Primary consumer: usually herbivores, animals that eat plants and algae. (caterpillar) 2nd level consumers- Secondary consumer: usually carnivores, animals that eat the primary producers. (lizards) 3rd level consumers- Tertiary consumer: animals that don’t have predators, they are considered the top of the food chain. (birds of prey, hawks, falcons, eagles, owls)

16. Organisms Organisms adapt to abiotic and biotic factors in their home Abiotic: non living parts of an ecosystem (sun, water, air) Biotic: means “pertaining to life”, the living members of the community Animals respond to cold conditions with a period of lowered metabolism (hibernation) Organisms may respond to adverse conditions with a period of lower or suspended metabolism (dormancy)

17. Abiotic & Biotic

18. Ecosystems & Biomes Examples of ecosystems are forests, tidal pools, ponds Ecosystems, living communities, and their physical environment are functional units within the biomes Each major biome include climate range, and how well organisms have adapted Biomes are smaller divisions of ecosystems Organisms have specific structures, functions, and behaviors that enable them to survive the conditions of a particular biome

20. Carbon Dioxide Cycle In the carbon dioxide-oxygen cycle, producers release oxygen for consumers who release carbon dioxide for the producers (Photosynthesis).

21. Water Cycle The parts of the water cycle are transpiration, evaporation, condensation, precipitation, runoff and infiltration.

22. Nitrogen Cycle Nitrogen cycle is the circular path in which nitrogen moves through the environment. Nitrogen is a gas that makes up 78% of the earth’s atmosphere. 1.Nitrates (made by nitrogen converters) are a combination of oxygen and nitrogen, absorbed by the roots of plants. 2.Nitrifying bacteria converts ammonia from dead plants and animals and animal waste to nitrates that can be used by plants. 3.Denitrifying bacteria converts ammonia from dead plants and animals and animal waste into Nitrogen, which is released into the atmosphere. 4.Ammonia is a gas given off by dead plants and animals waste.
