An Introduction to Ecology
1. What I love about the planet earth is the nature (plants, trees, animals, oceans etc)
2. I think it was because
3. An aquarium is a complete world in itself. Plantslive together with animals in one place.
4. All living things that depend on each other and their environment.
5. These relationships of interaction and interdependence between living organisms andtheir environment are studied in the branch of biology known as ecology.
6. Abiotic: grains, water particles, wind, current, precipitation, underwater caves, sand.
Biotic: seaweed, fish, mammals,animals.
7. Ecologists call a specific place an ecosystem when all the living organisms and nonliving factors in that one place are considered together.
8. Many rain forest trees have shallow rootsystems. To support themselves upright, these trees have wide supports called buttresses.
9. The stem of the cactus, once it is swollen with water, can keep the plant alive throughout the long drymonths ahead.
10. Adaptations are the characteristics of an organism that give it this fit.
11. The place where an organism lives is its habitat.
The occupation of an organism is called its niche.
12.Natural Selection is the process by which the organisms that are best adapted survive.
13. Ex: the availability of sunlight is an important limiting factors.
14. Because below that depth, it is toodark for plants to grow.
15. Deciduous trees, such as maples, have large, flat leaves.
Coniferous trees, such as pines, have narrow leaves called needles.
16. Fertilizers increase the amount ofnitrogen and phosphorus to levels needed by the crops.
17. Organisms have a tolerance range, sometimes a very narrow one. The amount of an environmental factor should be either too low nor too high.18. No, earth is really a water planet.
19. One of the main reasons that life exists on earth, and probably not on other planets in our solar system, is that only the temperature present on earth...
