1

Which of the following members of the food chain are most alike?

65% Answer Correctly

herbivores and autotrophs

primary consumers and omnivores

producers and tertiary consumers

scavengers and decomposers


Solution

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.


2

In the food chain, bacteria and fungi convert the organic matter in the dead bodies of plants and animals into simple nutrients. Bacteria and fungi are:

86% Answer Correctly

producers

scavengers

primary consumers

decomposers


Solution

Decomposers (saprotrophs) are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals into simple nutrients.


3

Leafy vegetables, beans, potatoes, fruits, and whole grains are good sources of:

81% Answer Correctly

unsaturated fat

fiber

protein

saturated fat


Solution

Fiber provides bulk to help the large intestine carry away waste. Good sources of fiber are leafy vegetables, beans, potatoes, fruits, and whole grains.


4

An element in the physical state of __________ maintains a constant volume and shape.

86% Answer Correctly

gas

gel

solid

liquid


Solution

An element in a solid state has atoms or molecules that are constricted and do not move freely. Solids maintain a constant volume and shape and exist at a lower temperature than liquids or gases.


5

Which of the following is not a characteristic of the Sun?

52% Answer Correctly

is composed of hydrogen and helium

formed 2.6 billion years ago

makes up over 99% of the mass of the solar system

is a yellow dwarf star


Solution

The Sun is a G-type main-sequence star (G2V) but is informally known as a yellow dwarf star. Composed of 73% hydrogen and 25% helium, the hot plasma that makes up the Sun reaches 9,900°F (5,505°C) at the surface. It formed approximately 4.6 billion years ago and makes up 99.86% of the mass in the solar system.
