A fungus grows around plant roots and allows the plant to absorb more water and nutrients. The fungi gets nutrients from the plant's roots. Which type of symbiotic relationship is demonstrated?
What is mutualism

Footpaths and vehicles destroy the plant life on the top layer of permafrost in the tundra biome. Which change is a result of losing plant life? A. increase in soil erosion B. increase in precipitation C. increase in frost formation D. increase in wildlife habitats
A. Increase in soil erosion- (plants keep soil from being washed away during heavy rainfall because of the roots)

Oxpeckers are a type of bird that feed on pests like the ticks and flies found on animals like zebras and giraffes. The oxpeckers also help keep wounds on animals clean and free from maggots, thereby reducing the chance of infection. What symbiotic relationship is this?
What is Mutualism

Eland are large herbivores with loose skin under the throat and neck. This patch of skin aids in lowering the body temp when outside temps are high. Eland are able to run fast and at long distances in their open environment. Eland are found in large herds. Which biome would you find these animals?
grassland

The northern elephant seal was almost hunted to extinction in the 1800's. By the late 1890's, approximately one hundred seals were left, reducing the gene pool of the population. What what was the consequence of this reduction? A. competition increased B. surviving seals would be able to adapt better C. inbreeding will be less D. elephant seals be more vulnerable to environmental change
D more vunlnerable

If you see the food chain below, which organism is harmed the most by a pollutant such as mercury? zooplankton -->shrimp -->fish -->crab
crab (biomagnification states that polluntant are passed through food chains with each level up receiving more amounts of the pollutant due to the larger organisms eating more of the smaller organisms thus consuming more amounts)
500
the food chain below would likely be found in which biome? Seeds --> mice --> black snake --> hawk
What is temperate forest
