Explanation:

To solve the crossword, we analyze each clue:

Across Clues:

1. center of earth, made of iron and nickel → Core (Earth’s center, metallic).
2. system where energy but not matter is exchanged with surroundings → Closed (Closed system: energy exchange, no matter).
3. enters the soil and water when rock breaks down in this cycle → Nutrient (Nutrient cycle: rock breakdown releases nutrients).
4. makes up 78% of atmosphere → Nitrogen (Atmosphere is ~78% nitrogen).
5. thin outermost zone of the earth → Crust (Earth’s thin outer layer).
6. earth’s actual shape → Oblate (Earth is an oblate spheroid).
7. sequence in which organisms consume others → Foodchain (Food chain: organism consumption sequence).
8. largest population an environment can support → Carryingcapacity (Carrying capacity: max population).
9. community of organisms and their abiotic environment → Ecosystem (Ecosystem: biotic + abiotic components).
10. break down dead organisms → Decomposers (Decomposers: break down dead matter).

Down Clues:

1. layer of earth that flows under pressure → Mantle (Mantle flows (plastic) under pressure).
2. related objects that interact to create a whole → System (System: interacting components).
3. condensation, precipitation, and evaporation make up this cycle → Water (Water cycle: includes these processes).
4. make their own food → Producers (Producers (e.g., plants) make food).
5. get energy from eating other organisms → Consumers (Consumers eat other organisms).
6. carbon dioxide and glucose make up this cycle → Carbon (Carbon cycle: involves CO₂ and glucose).
7. relationship between food chains → Foodweb (Food web: interconnected food chains).
8. group of processes where matter moves through reservoirs → Cycle (Cycle: matter movement through reservoirs).
9. force of attraction between all objects → Gravity (Gravity: universal attraction).
10. part of crust and upper part of mantle → Lithosphere (Lithosphere: crust + upper mantle).
11. system in which matter and energy are exchanged with surroundings → Open (Open system: matter + energy exchange).
12. layer of earth that makes up 2/3 of earth’s mass → Mantle (Mantle is ~2/3 of Earth’s mass).

Filling the Grid (Key Answers):

• Across 5: CORE
• Across 8: CLOSED
• Across 13: NITROGEN
• Across 15: CRUST
• Across 20: ECOSYSTEM
• Down 1: MANTLE
• Down 3: WATER
• Down 4: PRODUCERS
• Down 6: CARBON
• Down 11: GRAVITY
• Down 12: LITHOSPHERE

(Note: Adjust for grid spacing/lengths; e.g., “Carryingcapacity” is one word, “Foodchain”/“Foodweb” as single words, etc.)
