Question 4
Clouded leopards are a medium-sized, endangered species of cat, living in the very wet cloud forests of Central America. Assume that the normal spots (XN) are a dominant, sex-linked trait and that dark spots are the recessive counterpart.

Suppose, as a Conservation Biologist, you are involved in a clouded leopard breeding program. One year you cross a male with dark spots and a female with normal spots. She has four cubs and, conveniently, two are male and two female. One male and one female cub have normal spots and one each have dark spots.

Which explains how the biomass at the top of the pyramid will change if a fire destroys a large percentage of the grasses in this ecosystem?

a
It will increase because the amount of energy lost as heat between the first trophic level and second trophic level will decrease.
b
It will increase because the fire increases the efficiency of energy transfer and prey aquisition at higher trophic levels.

The Greenhouse Effect

The greenhouse effect is the process through which is trapped near Earth's surface by substances known as 'greenhouse gases.' Imagine that these gases act like a blanket surrounding our planet, helping to maintain a than it would have otherwise. Greenhouse gases include , methane, ozone, nitrous oxide, chlorofluorocarbons, and water vapor.



Scientists have determined that plays a crucial role in maintaining the stability of Earth's atmosphere and global temperatures. Greenhouse gases are a vital part of the atmosphere, and in maintaining life on Earth. However, in the last century, human activities, primarily from burning have led to the increased release of carbon dioxide. This carbon had been stored deep below the surface of the planet. Digging up and burning these fossil fuels have disrupted Earth's atmospheric balance. This has led to an increase in carbon dioxide in the atmosphere and ocean. Levels of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and trap extra heat near Earth's surface, causing to rise, leading to human accelerated climate change.

Question 8
Invasive Joro spiders with yellow stripes increase in GeorgiaMillions of giant spiders have invaded North Georgia since 2014, terrifying residents and spinning webs as thick as 10 feet (3 meters) deep. The bright-yellow Joro spider, (Trichonephila clavata), is an invasive species originating in East Asia.

The Joro is a non-native species, and how could this "invasion" of Georgia harm our ecosystem?

Question 12
Nutrient Cycles in a Nutshell



Nutrient cycles, also known as cycles, describe the movement of chemical elements through different sources and processes, such as the atmosphere, soil, rocks, bodies of water, and organisms. Nutrient cycles keep essential available to plants and other living organisms. The of these elements is critical to maintaining life on Earth. The carbon cycle, the nitrogen and water cycle all have important phases. The cycle lacks a true phase, and is slow and depends on the water cycle, also called the cycle.

Question 24
The passage describes chemosynthetic bacteria, and the diagram models a basic food web.

Deep below the surface of the ocean are communities that thrive without even a trace of sunlight. The trick is something called chemosynthetic bacteria. These bacteria are released by hydrothermal vents on the ocean floor, which are vents that are very hot and are able to chemically produce their own energy. Very small organisms, like tube worms, shrimp, mussels and clams, come to feed on the bacteria from the vents. Then, there are crabs that eat the bacteria but also eat shrimp, mussels, clams, and tube worms. Last, there is the vent octopus, which will eat everything.


Which oceanic organism has a role most similar to that of the zebra?

a
chemosynthetic bacteria
b
hydrothermal vent
c
octopus
d
clam
