Carrying Capacity, Food Chains & Food Webs

Carrying Capacity (K) The maximum population size that can be supported by the available resources Limiting resources: Energy (food), shelter, refuge from predators, water, suitable nesting sites

During what year did the species reach its carrying capacity?

This graph above suggests that from 1840 to 1920, the carrying capacity for sheep in Tasmania was approximately — 0.75 million 1.00 million 1.75 million 2.25 million

Which explanation below is the best reason why the carrying capacity dropped during years 4 to 7? A.The animals began to migrate to another area in year 4. B.The animals began to have fewer offspring between years 3 and 4. C. A group of non-grass eating animals moved into this area in beginning in year 3. D.The area began to experience drought conditions in year 4.

Which of the following situations MOST likely produced this population of deer on WallaWalla Island? A. Deer predators were removed from the island before the deer arrived. B. The deer overgrazed the grasses immediately upon their arrival to the island. C. After a period of time the deer adjusted to the available food on the island. D. The deer contracted a new disease just after their arrival on the island.

This graph below shows the sizes of lynx and hare populations between the years of 1845 and 1940. If a predator of the lynx enters the food chain, you might expect the number of — lynx and hares to become equal lynx to increase hares to increase hares and lynx to decrease

Food Chains Sequence of who eats whom Food Chain starts with _______________. What happens to energy as it moves through food chain? Use _________________ to show the flow of energy through a food chain

Food Chain Terms Put the following terms in correct order Quaternary Consumer Energy Source Primary Producer Tertiary Consumer Primary Consumer Secondary Consumer

Food Chain 1 Use the following terms & organisms Put in correct order in a food chain Quaternary Consumer Energy Source Primary Producer Tertiary Consumer Primary Consumer Secondary Consumer Sun Hawk Snake Grass Grasshopper Rat

Food Chain 2 Quaternary Consumer Energy Source Raccoon Primary Producer Tertiary Consumer Primary Consumer Secondary Consumer Raccoon Sun Algae Fish Dragonfly larva Mosquito larva

Food Chain 3 Quaternary Consumer Energy Source Zooplankton Sun Primary Producer Tertiary Consumer Primary Consumer Secondary Consumer Zooplankton Sun Phytoplankton White Shark Fish Seal

Food Chain 4 Energy Source Owl Primary Producer Sun Tertiary Consumer Primary Consumer Secondary Consumer Owl Sun Grasshopper Grass Frog

Phytoplankton are extremely diverse, varying from photosynthesizing bacteria (cyanobacteria), to plant-like diatoms, to armor-plated coccolithophores (drawings not to scale). (Collage adapted from drawings and micrographs by Sally Bensusen, NASA EOS Project Science Office.) Like land plants, phytoplankton have chlorophyll to capture sunlight, and they use photosynthesis to turn it into chemical energy. They consume carbon dioxide, and release oxygen. All phytoplankton photosynthesize, but some get additional energy by consuming other organisms.
