Melaku Michael (ethiomelaku2) Ecology Review—Honors Biology Copy and paste the questions into a word processing document. Answer the questions, then place in the Unit 8: Ecology Review Sheet (H). Make sure you either type your answer in a different color or highlight your answer. 1. What are a biotic and biotic factors and provide several examples of each. A biotic factors are non-living factors and biotic factors are living factors. 2. Define each of the following and give examples of each: a. Population: the same species b. Community: the entire ecosystem c. Ecosystem: the entire population d. Biome: the entire world e. Biospherethe entire ecosystem . For each of the following symbiotic relationships, briefly describe and provide examples: a. commensalism: when one is good and other is bad b. mutualism: when one is good and other is good c. parasitism: one is bad and one is none What is the difference between an autotroph and a heterotroph and how do each obtain energy? 3. 4. Auxotroph makes its own food and heterotrophy does not. 5. What is an organism’s niche? How the organism relates to an environment 6. What is meant by predator-prey relationship? What factors may contribute to it and how do the two effect other populations? Be able to explain the “Oh, Deer!” lab. Predator prey relationship is that the prey eats the predator. 7. What is the relationship of trophic levels and food chains? Tropic levels are dealing with where the animal lives and food chain is who is eatien. 8. How much energy is transferred to higher trophic levels? 10% 9. List, briefly describe, and give examples of the five types of heterotrophs: . Dog, lion, tiger, monkey, cat 10. How is weather related to climate? Becouse climate is basically long weather. 11. Explain the difference between primary and secondary succession. Primary succession is he first move and secondary is the second move to a new location. 12. Describe the process of primary succession to a climax community regarding plant and animal species. The climax s stable. 13. What is carrying capacity how is it related to biotic potential, where is it on a growth? Carring capacity is how many animals can live an a environment, 14. For each type of limiting factors, briefly describe and give examples: a. Density-independent: desease b. Density-dependent: hurricane 15. What is the difference between intraspecific and interspecific competition and how could each affect populations? Intra=same inter=different species 16. What is meant by biotic potential? How much food and other recources is available er animal. 17. Define estuary. A water area formed when river meets ocean 18. What are three types of freshwater wetlands? Ocea, lake, river. 19. Identify these ocean zones: photic, aphotic, intertidal, coastal, open ocean, benthic Phoic zone ligh enters, aphotic zone no light. Intertdal zoe nea land. Coastal. Off land. Pen ocean middle of no wear Benthic all the way to the bottom, 20. How does climate determine biodiversity of biomes? Because some animals live in different tempretures. 21. 22. 23. 24. 25. How is DDT related to biomagnification? Because its pollution What causes acid rain? Pollution List contributing factors to the hole in the ozone layer and possible consequences of its depletion. What is meant by global warming? Earth is hot Explain what is implied by the “greenhouse effect” and what causes it? When gasses accumulate in the earhs atmoshphere and cause an effect where it is countinualsy being changed.
