It allows a population to grow at its biotic potential: D.) It determines the carrying capacity of the habitat concerned . 2.) Identify the statement about per capita growth rate that is not correct. A.) It does not depend on the period for which the population is under consideration. B.) It is used to compare populations of the same species but of different sizes. C.) It is independent of the initial size of population under study. D.) The change in population size can be expressed as the rate of change per individual in terms capita growth rate. 3.) Biotic potential is the highest possible per capita growth rate for a population. Which of the following would limit…

Question: Think and research the effects of humans' buildings structures, communities, etc. on undeveloped land. Particularly, look at natural species in Texas, as well as the physical environment.

Problem: What is the primary cause of the endangerment of  Varanus mabitang (Panay Monitor Lizard)? Hypothesis: habitat loss due to deforestation causes more endangerment of Varanus mabitang. As humans cut down the forests, These lizards lose habitat and prey that they need to survive. Question: How would you test your hypothesis? State the methods you think are appropriate to test your hypothesis.

8th Grade Science STAAR Review Category 4: Organisms and Environment TEKS 8.10B investigate how organisms and populations in an ecosystem depend on and may compete for biotic and abiotic factors such as quantity of light, water, range of temperatures, or soil composition Readiness Standard Baleen whale Smaller loothed whales Sperm whales Penguins Elephant seal Leopard seal Other seals Other birds Fish Carnivorous zooplankton Other herbivorous zooplankton Krill Phytoplankton 1. Which 3 organisms are in competition for carnivorous zooplankton? 2. How will the leopard seal population be affected if the penguin population declined? 3. Which would be more affected by a decrease in the krill population -"other seals" or "other birds"? Why? 4. Name 3 abiotic factors that the organisms in the food web above would compete for.

some of the Adélie colonies in this area. Which statement is supported by both the text and the excerpt above? All three penguin species, Chinstrap, Adelie, and Gentoo, live only on sea ice. The food supply for Adelie penguins includes both fish and krill in the Antarctic seas. Adelie penguins are dependent on the existence of sea ice for access to their food supply. Temperatures in the Antarctic have increased substantially in the last 60 years.

Part III: Food Web Regents Practice Base your answers to questions 1 through 3 on the information and passage below and on your knowledge of biology. Snowy Owls Move to the South Snowy owls are large white birds that normally inhabit the cold northern regions of Canada. Recently, scientists and birdwatchers have sighted the snowy owls much farther south than usual. When snowy owls are in northern areas, they feed on lemmings (small rodents). When lemmings are not available, as in the areas further south, the owls will seek out mice or rabbits as their food source. Several snowy owls migrated into an area represented by the food web below Level с Level B Level A Mountain lions Elk Trees Snakes Rabbits Mice Hawks Frogs Crickets Grasses 1 Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of the snowy owls and explain why their population would be affected.
