Tropical Ecosystems

Tropical Ecosystems Tropical Rain Forests

tropical rain forests grow along the equator an area that has a lot of rainfall and high temperature all year climate: average weather over a long time, allows many plants to grow well rain-forest trees grow tall form canopy (roof) leaves shelter the area below, blocking most of the sunlight many plants and animals live high in canopy use sunlight and open spaces

tropical rain forests grow along the equator

an area that has a lot of rainfall and high temperature all year

climate: average weather over a long time, allows many plants to grow well

rain-forest trees

grow tall

form canopy (roof)

leaves shelter the area below, blocking most of the sunlight

many plants and animals live high in canopy

use sunlight and open spaces

rain forest floor home to plants that grow well in shade plants that need lots of sun can only grow where a tree has fallen and there is an opening in the canopy rotting plant material covers floor decomposers at work rain forest depends on decomposing and recycling of nutrients takes place on forest floor

rotting plant material covers floor

decomposers at work

rain forest depends on decomposing and recycling of nutrients

takes place on forest floor

animals and plants in rain forest great diversity: variety most plant and animal species than any other ecosystems on Earth tree top habitats for thousands of species mammals play on sturdy tree limbs (spider monkey, lemur) birds nest on branches (toucans, macaws) butterflies drink nectar from orchids that grow on tree branches

great diversity: variety

most plant and animal species than any other ecosystems on Earth

tree top habitats for thousands of species

mammals play on sturdy tree limbs (spider monkey, lemur)

birds nest on branches (toucans, macaws)

butterflies drink nectar from orchids that grow on tree branches

Coral Reefs ecosystems located in tropical climates near equator plenty of sunlight warm, clean water year round constant salinity (amount of salt in water) all conditions needed for coral reef to grow

constant salinity (amount of salt in water)

all conditions needed for coral reef to grow

coral reef made of rocky skeletons of tiny animals called corals live in colonies different sizes, shapes, colors big, fan shaped leaf or giant brain coral colonies are made up of tiny soft-bodies animals called polyps no bigger than your thumb young colonies only have a few polyps/older ones have millions of polyps

coral reef made of rocky skeletons of tiny animals called corals

live in colonies

different sizes, shapes, colors

big, fan shaped leaf or giant brain

coral colonies are made up of tiny soft-bodies animals called polyps

no bigger than your thumb

young colonies only have a few polyps/older ones have millions of polyps

coral polyps build limestone skeletons around their bodies take calcium out of sea water flower-like tentacles (arms) reach out from skeletons trap small plants/animals sting prey pulled into coral’s mouth algae that lives inside skeleton also provides nutrients

coral polyps build limestone skeletons around their bodies

take calcium out of sea water

flower-like tentacles (arms) reach out from skeletons

trap small plants/animals

sting prey

pulled into coral’s mouth

algae that lives inside skeleton also provides nutrients

when polyp dies - skeleton is left another polyp moves in and adds more limestone coral reefs grow for many years holes, branches, and layers of reef places for animals to rest some animals are bright and easy to see: angelfish, striped butterfly fish, and sea horses some animals are hard to see: flat flounders, scorpion fish each animal has it’s habitat and niche in the coral reef ecosystem

Resources from the Tropics tropical rain forests and coral reefs are homes to thousands of species of organisms found no where else on Earth from these organisms come hundreds of different products that people needs and use
