Explanation:

To solve the crossword puzzle about the characteristics of living things, we analyze each clue and use the word bank and grid:

Across Clues:

1. Thirst is an internal stimulus (thirst is a stimulus from within the organism).
2. Organisms that consume other organisms for energy are heterotrophs (heterotrophs rely on other organisms for food).
3. All living things are made of cells (basic unit of life).
4. One of the primary chemicals necessary for life (most abundant) is water.
5. Living things need energy (to perform life processes).
6. Living things respond to their surroundings (react to stimuli).
7. Organisms composed of only one cell are unicellular.
8. Organisms that make their own food are autotrophs (e.g., plants).

Down Clues:

1. Living things are composed of chemicals/molecules (living matter is made of chemical compounds).
2. Organisms composed of many cells are multicellular.
3. External stimuli come from outside the organism (e.g., light, temperature).
4. Living things have the ability to grow (increase in size/complexity).
5. An action or change in behavior due to a stimulus is a response.
6. Living things have the ability to develop (mature/change over time) and grow (note: the clue mentions “and develop,” so the first part here aligns with growth/development, but the grid for 12 likely fits “grow” or similar—adjusted for grid length, but based on clues, “grow” or “develop” contextually, but the grid’s 12-down likely fits with the theme of growth/development).

Filling the Grid (Key Entries):

• Across 1: INTERNAL
• Across 5: HETEROTROPHS
• Across 7: CELLS
• Across 8: WATER
• Across 11: ENERGY
• Across 13: RESPOND
• Across 14: UNICELLULAR
• Across 15: AUTOTROPHS
• Down 2: CHEMICALS (or MOLECULES)
• Down 3: MULTICELLULAR
• Down 6: EXTERNAL
• Down 9: GROW
• Down 10: RESPONSE
• Down 12: GROW (or DEVELOP, but grid length matches “GROW” or similar—adjusted for the puzzle’s filled letters).

For example, the pre - filled “cells” (Across 7) and “water” (Across 8) and “respond” (Across 13) align with the clues. The remaining clues follow the same logic of matching the characteristic of living things to the word bank and grid structure.

If you need specific help with a single clue (e.g., a blank you’re stuck on), share the clue number, and we can refine the answer!
