Tuesday, May 9 Why is it so important for humans to have plants on Earth with us?
Photosynthesis: when plants use solar energy to make and store chemical energy as plant materials.
RESPIRATION: Animals using oxygen and sugar (chemical energy) to make mechanical energy
Put the following organisms in order for the food chain with arrows to show the energy flow: Wolf, sun, flower, grasshopper, bird, bear, raccoon.

NegativeHuman Influences on Ecosystems Habitat Destruction Human development Deforestation Land Loss/Desertification Non-native Species/Invasive Species Competition for Resources Over Harvesting fishing/hunting 5. Pollution/Global Warming Air and Water
Positive Human Impacts on the Ecosystem Making wildlife animal refuges to increase the population of endangered species. Planting trees to reduce the impact of deforestation. Cleaning up the pollution of rivers and oceans. Reduce, Reuse, Recycle
Niche: Unique role, or job, of a species within an ecosystem Niche: Unique role, or job, of a species within an ecosystem. How it uses its habitat to survive. Habitat: Location https://www.youtube.com/watch?v=xIVixvcR4Jc&spfreload=5
Competition: 2 or more organisms using the same resource in a habitat Competition: 2 or more organisms using the same resource in a habitat. Their niches overlap. Food, water, air, space needed to live long enough to reproduce and pass on genetics to the offspring. http://study.com/academy/lesson/symbiotic-relationship-definition-examples-quiz.html
Symbiosis: 2 organisms living in close association and at least one benefits from the relationship. https://www.youtube.com/watch?v=zTGcS7vJqbs https://www.youtube.com/watch?v=zSmL2F1t81Q
3 Types of Symbiotic Relationships Mutualism: both organisms benefit and help each other survive (win, win) Examples: Clown fish and sea anemone, bacteria in human intestines 2. Commensalism: one organism benefits and the other is not affected at all. (win, draw) Examples: Remora and Shark, bird nest in a tree 3. Parasitism: One organism benefits and one organism is harmed. (win,lose) Examples: ticks, fleas, tape worms, heart worms, leeches, mistletoe
