Asia                                                          52                  71,370,000
Africa                                                          3                    4,117,500
Europe                                                     18                  24,705,000
Latin America and the Caribbean              8                  10,980,000
Oceania                                                  <u>   2</u>                <u>    2,745,000</u>
                                                               100                137,250,000

We multiply the 137.25 million metric tons by its percentage to get its equivalent value in metric tons.

Asia uses 71.37 million metric tons.

In making the bar graph, The vertical line will be the percentage and the horizontal line will be the region. Bars of each region should have different colors for easy identification. Spaces between bars should be present, so that the bar graph will not be confused with the histogram.

Which of the following is a behavioral adaptation of the Venus fly trap?
Neko [114]


The correct answer is A - leaves that close when touched.

The Venus flytrap is a type of flowering plant that is best known for its unique adaptation to trap live insects using a trap.

The trap is made up of two hinged lobes at the end of each leaf, with hair like projections called trichomes that cause the lobes to snap shut when prey comes into contact with them.

This type of movement is called thigmonasty which is a non directional plant response to being touched.
