Question

name date period color by number - invasive species directions: answer the questions below by circling the correct choice. when you are finished answering all the questions, color in the picture with the color from your answer choices. any area not numbered is your choice. example: all of the number ones will be colored with the color you chose for the correct answer choice from question number 1. 1 a species that is not native to an area is called a(n) ____ species. invasive (green) non - native (red) native (blue) 2 why do the populations of an invasive species grow so quickly? they have no natural predators in the new area. they are native to the area. they are easy to move around. 3 a species that occurs naturally in an environment is called a(n) __ species. invasive (pink) non - native (dark blue) native (light pink) 4 domesticated animals like cats and pigs that become wild or feral are __ for the environment. good (light purple) bad (brown) neutral (red) 5 invasive species alter the ecosystem by __ in number quickly. this leads to __ food for the native species. increasing (blue) / decreasing (blue) decreasing (orange) / decreasing (orange) increasing (yellow) / more (yellow) 6 most invasive species do not survive in a new environment because they lack evolutionary __. genes (orange) adaptations (blue - green) survival skills (blue) 7 the primary cause of the introduction of invasive species is __. other wildlife (light blue) natural actions (dark blue) humans (light blue) 8 indigenous species are also called ____ species. native (beige) invasive (gray) non - native (purple) 9 an invasive species can have a major impact on an ecosystem. true (purple) false (dark blue) 10 invasive species grow quickly due to the lack of predators. this can decline or extinction of the native species. true (dark pink) false (purple)

Explanation:

To solve these "Color by Number - Invasive Species" questions, we analyze each one based on the concepts of invasive species (biology, ecology):

Question 1

A species not native to an area is invasive (or non - native, but "invasive" fits the term for non - native species that spread). So circle "invasive (green)".

Question 2

Invasive species populations grow quickly because they have no natural predators in the new area. So circle "They have no natural predators (red)".

Question 3

A species occurring naturally in an area is a native species. So circle "native (light pink)".

Question 4

Domesticated animals (like cats, pigs) going wild are bad for the environment (they compete with native species). So circle "bad (brown)".

Question 5

Invasive species increase competition, so they decrease food for native species. So circle "decreasing (orange)".

Question 6

Invasive species that don’t survive lack adaptations to the new environment. So circle "adaptations (blue - green)".

Question 7

Humans are the main cause of introducing invasive species (e.g., trade, release). So circle "humans (light blue)".

Question 8

Indigenous species are native species. So circle "native (beige)".

Question 9

Invasive species do have a major impact on ecosystems (e.g., outcompete natives). So circle "True (purple)".

Question 10

Invasive species grow quickly due to lack of predators/parasites (no control), so the statement is True. Circle "True (dark pink)".

After answering, use the color from each answer choice to color the picture (e.g., question 1: green, question 2: red, etc.).
