-Bird of Paradise
-Poison Dart Frog
-Red Eyed Tree Frog
-More than 250 cm of rain
-Average temp 20-34 C
-Tall trees shade the floor so indirect light except above which is very direct
-The most of a species that an environment can support
-Can be abundant, but death, birth, and destruction of habitat diminish it
-Things that change an ecosystem
-Such as: Rain, Sunlight, and people cutting down trees
-When the sloth population goes up so does the Jaguar, once this occurs the Jaguars eat the Sloth causing a decrease in Sloth population, but once the food source shrinks so does the predator causing a increase in Sloth population
The graph shows that predator/prey occur every environment.
Producers, Consumers, Decomposers
-Producers: plants/organisms that make their own food
ex: coco tree
-Consumers: organisms that eat other organisms
ex:Jaguar (carnivore), Sloth (herbivores), Red Eyed Tree Frog (omnivore)
-Decomposers: organisms that break down dead waste
After an organism gets eaten 10% of the past energy is given to the predator. Producers are essential, because they start the food chain and get energy from the sun.
Food chains are less realistic than food webs, because food webs show multiple relationships.
-If one population was gone the whole food web would crash.
-The producer has 1000 kcal, and each time it goes up a level it loses 10% of the kcals. --This is shaped like a pyramid, because it loses energy as it goes up that's why the producers have the most energy.
-In photosynthesis carbon dioxide, water, and sunlight are needed. Photosynthesis produces oxygen and glucose.
-definition:turning or bending movement toward or away from an external stimulus
ex:trees growing with roots and trunk
The roots grow toward water and the leafs toward light.
-Decomposers give nutrients back into soil which these many trees need, without them the rain-forest would die
-Saprophytes are an example
Adaptations are important, because they keep animals alive and make life easier for them.
ex: large jaw muscles in jaguars to pierce skull
Venus fly traps snap their jaws closed with their super-sensitive hairs (adaptation).
If the plant was placed in a different ecosystem that was windy the hairs wouldn't be able to tell the difference between wind and insects. Then the plant would have to feel the weight of the insect and adapt.
-gradual process in which animals adapt over time
ex: sloth change from two to three toed
