  2. Desert Ecosystem • Has plants or producers that don’t need so much water to survive. They hold it for a long time. • If plants in the desert lived near the ocean or in the ocean, they would die due to too much water exposure. • Extremely arid climate. • Very warm at day, and very cold at night.

  3. Desert Ecosystem • Limiting Factors- not enough water, predation, and limited food. • Abiotic Factors- rain, sunlight, sandstorms, physical geography. • Predation- rattlesnakes eat rats. • Mutualism- bees pollinating cacti. • Competition- rattlesnakes compete for birds to eat.

  4. Desert Ecosystem Adaptations • Plants and animals store water, because they don’t need as much to survive. • Animals hunt at night, so it’s cooler. They rest in the day. • Predators get water from the bodies of their prey.

  5. Tropical Ocean Ecosystem • Most organisms are fish. • Producers aren’t all plants; Phytoplankton are producers. • Plants in the ecosystem need the moisture from the air and water or they won’t survive. • One of the largest ecosystems, has the most organisms, and isn’t fully explored. • Located in the low tropical latitude zones and mid latitude zones. • Very warm and moist climate. • Plants: Tropical terrestrial plants, seaweed and other underwater plants. • Limiting Factors include water pollution, predation and food.

  6. Tropical Ocean Ecosystem • Limiting Factors include water pollution, predation and limited food. • Abiotic Factors- Sediment, man-made contraptions. • Predation- Sharks kill other fish for food. • Commensalism- small fish swim underneath sharks, and when the sharks eat, small amounts of food fall for the fish to eat. • Parasitism- Barnacles live in the shells of crabs.

  7. Tropical Ocean Ecosystem Adaptions • The Stonefish developed a camouflage to avoid getting killed. • Whales are warm-blooded in order to survive the climate changes when they migrate. • Sea turtles have flipper-like legs and smaller shells to help them swim.
