Which of the following members of the food chain are most alike?
scavengers and decomposers |
|
producers and tertiary consumers |
|
herbivores and autotrophs |
|
primary consumers and omnivores |
Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
In the water cycle, infiltration is most closely related to:
rivers |
|
oceans |
|
runoff |
|
water table |
The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.
Which of the following is the correct order for types of radiation from lowest to highest frequency?
radio waves → visible light → gamma rays |
|
microwaves → radio waves → visible light |
|
visible light → ultraviolet light → radio waves |
|
infrared waves → microwaves → ultraviolet light |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
When the clouds become too saturated with water, the water is released as precipitation in the form of:
snow |
|
rain |
|
ice |
|
snow or ice |
Rising into the atmosphere, the water condenses into clouds. When the clouds become too saturated with water, the water is released as snow or ice precipitation which may warm as it falls to reach Earth as rain.
