Explanation:

To solve these biology - related questions (since they are about organisms, ecosystems, etc., which fall under the Natural Science discipline, specifically Biology), we'll address each sub - question:

Question 2

We need to find the habitat (aquatic or terrestrial) of the organism we choose. Let's say we choose a frog. Frogs start their life in water (aquatic) as tadpoles and then can live in both aquatic and terrestrial environments, but mainly as adults, they are more terrestrial near water bodies.

Step 1: Choose an organism (e.g., frog)

Step 2: Determine its habitat

A frog has an aquatic stage (tadpole) and a terrestrial - aquatic adult stage. But if we consider the main habitat for the adult, it's terrestrial (near water). For the aquatic part, tadpoles live in water.

Question 3

We have to identify the diet of the organism. For a frog, it's a carnivore as an adult (eats insects, small invertebrates) and as a tadpole, it can be herbivorous (eats algae). Let's focus on the adult frog.

Step 1: Choose the organism (frog)

Step 2: Determine its diet

Adult frogs are carnivores (eat insects, worms, etc.). Tadpoles are often herbivores (eat algae).

Question 4

We need to find a stimulus that the organism responds to. For a frog, temperature is a stimulus. When it's too cold, frogs hibernate; when it's warm, they are more active. Also, light (day - night cycle) affects their activity (nocturnal in many cases). Let's take temperature.

Step 1: Choose the organism (frog)

Step 2: Identify the stimulus

Temperature: Frogs are ectotherms, so they respond to temperature changes. In cold temperatures, they hibernate; in warm, they are active.

Question 5

Answer:

Let's take the cane toad again. Its original country is South America (specifically, it is native to Central and South America, with countries like Brazil, Venezuela, etc. in its native range).

Step 1: Identify the invasive species (cane toad)

Step 2: Determine its original country

The cane toad (Rhinella marina) is native to South and Central America, with countries like Brazil being part of its original range.

These answers are based on the study of organisms, ecosystems, and invasive species, which are core topics in the sub - field of Biology (under Natural Science).
