1
Ecology The study of living things and how they interact with their surroundings
2
Objectives Describe symbiosis
Describe how organisms conserve energy by migrating, compete, switching type of prey, hibernating, going dormant. Compare energy a hummingbird and coyote put out to get food in a cold and warm climate.
3
Objectives Research food production
4
The Biosphere The place where life exists, from the high atmosphere to the deepest ocean bottom
5
5 Kingdoms of Life Animals Plants Fungi Protista
Bacteria (Prokaryotes)
6
Population The number of species in one place and time 50,000 Cowbirds
7
Community The populations of different species in one place and time.
8
Ecosystem The plants, animals, fungi, protists, and bacteria that live in a certain area, and their unique non-living parts like temperature, soil, and daylight.
9
Aquatic Ecosystems Freshwater pond, lake, stream Ocean (saltwater)
Estuary (mix of salt & fresh water)
10
Terrestrial Ecosystems
Meadow Prairie Mountain Forest Desert Scrub Ecotone- area between two ecosystems

16
Objectives Relate Biotic and Abiotic factors in an ecosystem
Define niche, species, habitat, population, community, ecosystem, biome
17
Biotic Factors Identify the role of an autotroph, heterotroph, producer, consumer, decomposer in a matter cycle Describe symbiotic relationships mutualism, competition, commensalism, parasitism, predator-prey Describe feeding relationships herbivore, carnivore, omnivore, detritovore, scavenger
18
Abiotic factors affect living things
Rainfall affects the type of plants that will grow and thus creates the climate of an area (called a Biome)
19
Abiotic factors Soil type, Air currents, Temperature, Light, pH,
20
Temperature Temperature of soil, air, and water determine the type of organisms that grow. Too high or low of temperature can kill organisms Cantaloupe seeds need soil at 65-85F to germinate
21
Elevation Elevation changes the temperature
Elevation can allow more or less moisture to fall
22
Wind & Air currents Help seeds move to reproduce plants, fungi spores
Bring in rain or snow
23
Day length Day length can affect the type of plants that come out, or when they flower, or when they grow
24
Chemicals Chemicals affect growth of living things
Oxygen and Carbon dioxide help life Some living things make poisons to protect themselves
25
Chemicals... Acid and Base level, (measured in pH) can affect the type of life growing in an area Stomach acid is pH 1, Water is 7, Utah’s alkaline soil is 8, Drano is 14. Pine trees produce slightly acidic needles
26
Chemicals... Salt level, called salinity Most plants die in salt
Pickleweed (Salicornia virginica) and Saltbush (Atriplex) love salt
27
Field Trip Lab: How does day length influence flowers and birds?
Identify 5 abiotic factors and 5 biotic factors in Wetlands of the Great Salt Lake and Farmington Bay Wildlife Refuge Describe food chain and energy pyramid present in the bay. How is water a limiting factor in the bay? How do Brine Shrimp survive?
28
Autotroph A producer of its own food.
Plants, and some Blue Green bacteria and some protists like Algae make their own food from the Sunlight and Water or out of Chemicals in their surroundings
29
Heterotroph Eats another organism. Can’t make their own food so they eat a producer or another heterotroph.
30
Herbivore Heterotrophs Omnivores Carnivores Opportunists Scavengers
31
Decomposers
32
Decomposer Breaks down chemicals from dead or decaying material.
33
Mutualism Two different species benefit each other.
Ants and Acacia trees. The ants protect the tree from harm and the acacia tree provides nectar for the ants.
34
Clownfish and anemones
35
Lichen and Algae
36
Bristle worm and Hermit Crab
The bristle worm eats leftovers from the crab
37
Rhino & Tick bird
38
Commensalism One species benefits from another species but the other species is neither harmed nor benefitted. Spanish moss grows and supports orchids and ferns, but is neither helped nor hindered by the plants.
39
Remora & Shark
40
Parasitism One species benefits from a harmed species.
Fleas bite dogs and cats for food. Tape worms eat food from human and dog stomachs. Cowbirds lay their eggs in other bird’s nests and have the other birds feed their young cowbirds.
41
Mistletoe & Tree
42
Zombie Snails
43
Tapeworm
44
Predator-Prey An animal kills and eats another species.
Lion kills a zebra
45
Territory Many animals must have a certain area in which to find adequate food Deer live in 100 square kilometers Falcons, Hawks and Eagles like 10 square kilometers or more
46
Habitat- where an organism lives
Trout lay their eggs on certain types of soil- sandy or pebbly Dogs find holes in secret, hard to find cliffs to protect their pups Habitat- where an organism lives
47
Niche How organisms get food, where they live, and the adaptations they have that help them survive.
49
Coyotes
50
Hummingbirds
