• it is the scientific study the environment.

• it is the scientific study of animals.

______: the variety of organisms, the organism’s genetic differences, and the ecosystems in which they occur.

• Biodiversity

• Biome

• Biosphere

A ____ is a large group of many ecosystems.

• Population

• Biome

• Communities

• Ecosystem

_______ have the highest biodiversity of all the biomes because they are abundant in nutrients, energy and a favorable climate.

• Savannas

• Tundra

• Tropical rainforests

• Coral Reef

A pond ecosystem is shown in the diagram below. Which statement describes an interaction that helps maintain the dynamic equilibrium of this ecosystem?

• The frogs make energy available to this ecosystem through the process of photosynthesis.

• The algae directly provide food for both the rotifers and the catfish.

• The green-backed heron provides energy for the mosquito larvae.

• The catfish population helps control the populations of water boatman and waterfleas.

According to the food web, which of these supply energy for all the other organisms?   

• snake

• insects

• grasses

• cougars

Deforestation by burning has been described as a "double whammy" to the environment, meaning it has 2 negative impacts. Why is this description accurate? 

• Forest burning releases CO₂ while decreasing oxygen, which disrupts cycles

• Deforestation reduces the amount of oxygen in the atmosphere, which depletes the ozone layer

• Forest clearing is often followed by land development, which often leads to increased noise pollution

• Deforestation increases the number of plant and animal species by destroying habitat
