Biodiversity

Explore biodiversity & population dynamics! Our worksheet covers limiting factors, carrying capacity, and ecological levels. Practice science concepts.

Answer the following questions about population size and factors: List three (3) abiotic limiting factors in an environment. Fire, temperature, and soilList three (3) biotic limiting factors in an environment. Predation, reproduction, and food sourcesA group of the same organisms in a given location is called? PopulationThe amount of the same organisms in a given location is called? Population sizeThe amount of organisms that an environment can support is called? Carrying capacityDifferent forms of life in a given area is called? BiodiversityWhen organisms move out of a population, it is called? EmigrationWhen organisms move into a population, it is called? ImmigrationList two ways that a population can increase in size. Births and emigrationList two ways that a population can decrease in size. Deaths and immigration Ecological Organization Order the levels of ecological organization from largest to smallest: LEVEL DESCRIPTION DEFINITION Level 6 Biosphere Comprise all the levels of ecological organization and makes up the surface of the earth Level 5 Biome Comprise all the biotic and non-biotic factors in a given area, plus climate Level 4 Ecosystems Comprise all the biotic and non-biotic factors in a given area Level 3 Community Comprise of multiple (different) populations living in a given area Level 2 Population A group of the same species living in a given area Level 1 Organism A single living thing or species Biotic and Abiotic Factors Watch the video below. Then, list 8 biotic and 5 abiotic factors.Hint: Watch the entire video first. Watch the video above. Then, list 8 biotic and 5 abiotic factors. Hint: Watch the entire video first. Population Density Determine the population Density of each of the countries below: 3.29 136 337 328 16,205 81 247 34 Population Size - Kaibab Plateau Case Study - Deer In 1906, the Kaibab Plateau was established as a preserve to reestablish the deer population. Unfortunately, the Kaibab forest area had already been overgrazed by livestock, and predator populations were firmly established. As a result, the deer population was well below its carrying capacity of 30,000. To protect the deer, hunting was banned, predators were exterminated and livestock grazing was limited. By 1923, the deer were on the verge of starvation. Predators were then reintroduced and hunting was allowed.Answer the next five questions using the information above. Read the passage, analyze the table above, and answer the following question: Were the methods used to manage the deer population successful? Explain your reasoning. Read the passage, analyze the table above, and answer the following question: Were the methods used to manage the deer population successful? Explain your reasoning. Read the passage, analyze the table above, and answer the following question: Why did the population decline after 1925? Explain your reasoning. Read the passage, analyze the table above, and answer the following question: What factors influenced this growth pattern? Explain your reasoning. Read the passage, analyze the table above, and answer the following question: What is the carrying capacity of the deer population? Explain your reasoning. Population Size - Kaibab Plateau Case Study - Moose Moose first arrived at Isle Royale around 1900. The moose population tends to increase in years with mild winters, early spring green-up, abundant winter forage, low wolf numbers, and low levels of tick infestation. Wolves first arrived at the island on an ice bridge from Canada in 1940. Between 1980 and 1982, the wolf population declined from 50 to 14, due to canine parvovirus. Answer the next four questions using the information above. Read the passage, analyze the chart above, and answer the following question: What would happen to the moose population if the wolves were removed from the island? Read the passage, analyze the chart above, and answer the following question: What happens to the wolf population when the moose population decreases? Read the passage, analyze the chart above, and answer the following question: Identify 2 limiting factors that have influenced the wolf population. Read the passage, analyze the chart above, and answer the following question: What type of limiting factor are predator-prey relationships?
