Cheetah need a large lung capacity because they consume a lot of oxygen while sprinting.
Answer:
There are different methods of enumeration of bacteria like viable plate count, direct microscopic method, turbidity method, etc. These methods are used to find out the number and concentration of microorganisms in any sample.
In real like the application of using enumeration methods can be seen in diary microbiology, food, microbiology, water microbiology, etc. In these sectors, the enumeration method is used to find out the quality of the food items, water.
Water quality is checked by enumerating the number of coliform bacteria by serial dilution method. In food, bacteria that cause foodborne illnesses are enumerated by using the enumeration method.
Answer: B) Black bears, deer, and squirrels would undergo a mass extinction, so the forest’s biodiversity would decrease.
Limiting factor is a factor which limit the growth, distribution and abundance of population of one or more species in an ecosystem. A limiting factor can be natural or man-made. Natural limiting factor includes resources (food, shelter and water), abundance in predator population, natural disasters like landslide and earthquakes. Man-made limiting factors include deforestation, forest fires and nuclear explosions.
Here, oak trees can be considered as limiting factor. Oak trees are source of food resource in temperate deciduous forest. Cutting down of these trees will affect the populations of animals residing in the forest. As, populations of beer, black deer, and squirrels all rely on the acorns obtain from oak trees, cutting down of trees will result in mass extinction of black bears, deer, and squirrels. Hence, the diversity of animals in forest would decrease.
Fertile land is lost, and there is increased pollution and sedimentation in rivers and other aquatic areas.
