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 founta kel

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.
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.
Please do answers 4-7 these are the answers for the above : 1) Producers Consumers Herbivores Omnivores Predators Top predators Phytoplanktons, seaweeds All the other animals other than Phytoplanktons, seaweeds are consumers.

The original energy comes from the sun. The plants/producers convert light energy into chemical energy. 3. The longest food chain is - Phytoplankton - Zooplankton - Krill - Squid - Crabeater Seal - Killer whale
After completing the GVL OER module - Population Dynamics, explain the relationship between predator and prey. Identify the patterns that exist in the dynamic relationships between predator and prey. Relate your discussion to the overall health of their populations and ultimately the ecosystem. How does each organism benefit from the other? In what ways do other populations in the ecosystem benefit?
Case Study Skolnikland is in Eastern Africa, with a population of 30 million people. The country has a plains region, a hill region, and a region with high mountains. It has a number of ecosystems. The plains are dry for much of the year, there is some rainforest, and the rest of the country includes both hills and mountains. There are two seasons of heavy rainfall. The citizens come from several ethnic groups that tend to live in their own regions and speak different languages. The ethnic groups largely follow one of three different religions. The large cities are mixed ethnically. One ethnic group is economically and socially very dominant. The people from this group live in the capital and most of the large cities. The national language is the language of this dominant ethnic group. According to World Bank criteria, Skolnikland is among the poorest countries in the world. The economy has been growing at about 4% per year on average over the last decade, but the economy had very slow…

Part B- How does this research relate to your bialogy course? Biomes are major life zones characterized by vegetation and climate, primanily average temperature and precipitation Sort each characteristic to align with the appropriate biome. Hint: Review terrestrial biome information in your textbook or e Text. Greatest human impact is logging and land clearing for agriculture and urban development Large variation in annual preoipitation but with high annual temperatures Located along or near the equator Located at high latitudes in the northern hemisphere Greatest human impact is rapid population growth leading to habitat destruction Greatest human impact is destruction of forests through logging Significant precipitation throughout the four seasons Located at midlatitudes, mostly in the northem hemisphere Relatively low annual temperatures Tropical forest Temperate broadleaf forest Northern coniferous forest
