This project explores the distinct ecosystems of the savannah and the tropical ocean, highlighting their abiotic and biotic factors. In the savannah, key abiotic factors include fire, rainfall, and soil type, while its biotic components feature shrubs, grasses, and iconic wildlife like cheetahs and gazelles. The tropical ocean, characterized by salt and various marine organisms like sharks and sea turtles, faces differing limiting factors, such as temperature and run-off. We also examine how organisms in both ecosystems have adapted uniquely to their environments and the symbiotic relationships present.

  1. Ecosystem Comparison Project By: Amy Oliver and Kaitlyn Barth

  2. Abiotic factors of the savannah and tropical ocean • Savannah : fires, rainfall, drought, and soil. • Tropical Ocean : rocks, salt, sand, and water.

  3. Biotic factors of savannah and tropical ocean • Savannah: Shrubs, tall grasses, trees, cheetahs, and gazelles • Tropical Ocean: Phytoplankton, sharks, seaweed, turtles, crabs, and kelp

  4. Limiting factors of the tropical ocean • Temperature • Current Direction • Run-off from land

  5. Limiting factors of savannah • There is little water to be found because of the dry climate. • The amount and form of precipitation can cause grass fires. • The dry season does not last very long, and plants die out.

  6. Adaptations of organisms in tropical oceans • Sharks- They are able to breathe easily underwater. • They have teeth that are adapted to their types of meals. • They have a great sense of smell and sight which makes for easier hunting. • Crabs- They have hard shells which protect their internal organs. Eyes that can see both forward, and backwards. • Antennae that help sense prey and predators. • Jellyfish- Made up of 90% water, causing it to float easier. Large tentacles which help them put food into their mouths. They use their stinging cells to kill prey.

  7. Adaptations of organisms in the savannah • Gazelles: Able to get water for the food they eat. • Capable to live out in sun due to capability of keeping fluids. • Zebra: Can run up to 40 mph to escape predators. • Theory says that zebra’s black and white stripes confuse predators. • Elephant: Flap their ears to stay cool in the heat • Tusks help them dig and fight • Long trunks help them pick up water so they can spray themselves to keep cool.

  8. Symbiotic relationships in the savannah • A lion eats a wart hog . This is an example of predation. • A zebra and a hippo are fighting over grass. This is an example of competition. • There is a flea on an African Wild Dog. This is an example of parasitism.

  9. Symbiotic Relationships of tropical ocean • A shark eats a bait of fish. This is an example of predation. • Plankton clinging onto a fish. This is an example of parasitism • A fish eats seaweed, and seaweed grow back. This is an example of commensalism.
