comfortable or suitable place your time you spend. 3. ________ is the environment, like your neighborhood, whereas the ______ is like your home, a comfortable or suitable place your time you spend. As with homes on a street, habitats are often _____________ in ways that allow different types of organisms to reside in close proximity without getting in each others’ way. Habitat niche partitioned Identify the location of the anole lizards in their niche

Different species of Warblers are able to live in the same habitat/tree because _________________________ they occupy different niches

Terrestrial (land) Biomes 4 Tropical Rainforest Savanna/Grasslands Desert Dry, seasonal temps, sparse vegetation Warm, Seasonal wet/dry, fire-adapted grasses, herbivores very wet always warm great diversity Terrestrial (land) Biomes Deciduous Forest Coniferous Forest/Taiga Tundra Gymnosperms (cone-bearing trees), cool to cold year round Adequate rain, seasonal temps, plants go dormant in winter, shed leaves Permafrost, low lying vegetation, Cold year round

Aquatic Biomes 5 Ponds, Lakes Freshwater Streams, Rivers Biomes Wetlands Marsh, Swamps, Bogs Oceans Marine Biomes Coral Reefs Estuaries

Food relationships - continued f. _______________ (potential food) 1. ___________ - make their own food __________ - ________ 2. ___________ - depends on an outside source for food __________ a. _________ - eat plants b. _________ - eat meat (other animals) c. _________ - eat both plants and animals d. _________ - eat dead and decaying plants/animals ___________ Trophic Levels Autotrophs (producers) plants Heterotrophs (consumers) Herbivores Carnivores Omnivores Detritivores (decomposers)

Energy Pyramid What pattern do you see with the amount of energy moving to the next trophic level?

What is the difference between a food chain and a food web? How many tropic levels are shown? What is the producer? Consumer - herbivore, carnivore, omnivore? What is the difference between a food chain and a food web?
