Define an ecosystem in simple terms

• How do living and non-living things interact in an ecosystem?

  They help each other survive and thrive.
• What is the name of the sixth biome shown in the image?

  Mediterranean
• What happens when plants and animals die in an ecosystem?

  • Decomposers (biotic) break them down
  • Nutrients are added to the soil (abiotic)
  • This process helps new plants grow
• What is the name of the first biome shown in the image?

  Tropical Rainforest
• What components make up an ecosystem?

  • Living things (plants and animals)
  • Non-living things (air, water, sunlight)
  • Interactions among all components
• How do biotic components relate to abiotic components in an ecosystem?

  Biotic components rely on abiotic factors for survival
• What are the key features of mountains as an ecosystem?

  • Vertical temperature gradient
• What is the metaphor used to describe an ecosystem?

  An ecosystem is like a big team working together.
• What are the key characteristics of a tropical rainforest biome?

  • High temperatures year-round (25-35°C)
  • High rainfall (over 2000 mm per year)
  • Lush, dense vegetation with tall trees
  • High biodiversity with many species
• What do animals need from abiotic components to survive?

  • Animals (biotic) drink water (abiotic)
  • Animals breathe air (abiotic)
• What is the role of decomposers in an ecosystem?

  They break down dead organic matter
• What are the key characteristics of a coniferous forest (taiga) biome?

  • Long, cold winters and short, cool summers
  • Low precipitation (300-900 mm per year)
  • Dominated by evergreen coniferous trees
  • Low biodiversity compared to other forest biomes
• What is an ecosystem?

  A community of living and non-living things
• What elements are included in a pond ecosystem?

  • Plants
  • Fish
  • Insects
  • Water
  • Rocks
  • Sunlight
• What is the name of the third biome shown in the image?

  Coniferous Forest (Taiga)
• How do the roles of producers, consumers, and decomposers differ in an ecosystem?

  • Producers (e.g. plants, cyanobacteria) make their own food through photosynthesis
  • Consumers (e.g. herbivores, carnivores, omnivores) obtain energy by consuming other organisms
  • Decomposers (e.g. fungi, bacteria) break down dead organic matter and recycle nutrients
• What are the key features of the Mediterranean ecosystem?

  • Hot, dry summers
  • Mild winters
• What is the function of producers in an ecosystem?

  They make food for other organisms
• What are the key features of the temperate forest ecosystem?

  • Moderate climate
  • Deciduous trees
• What are the main components of an ecosystem?

  • Living things (animals and plants)
  • Non-living things (sunshine, water, rocks)
• What is the name of the fifth biome shown in the image?

  Temperate Grassland
• What roles do different parts play in a pond ecosystem?

  Each part helps keep the pond healthy
• What is the name of the second biome shown in the image?

  Temperate Forest
• If an ecosystem has a high number of decomposers, what might that indicate about the ecosystem?

  There is a lot of dead organic matter to be broken down
• What are the key features of the tundra ecosystem?

  • Cold climate
  • Permafrost soil
• What role do decomposers play in an ecosystem?

  They break down matter
• What is the significance of abiotic factors in an ecosystem?

  They are essential for the survival of biotic components
• What are the biotic components of an ecosystem?

  • Producers: Plants, algae, bacteria making food
  • Consumers: Animals eating other organisms
  • Decomposers: Fungi, bacteria breaking down matter
• What are the key features of grasslands?

  • Open areas
  • Dominated by grasses
  • Few trees
• What are the key features of the tropical rainforest ecosystem?

  • Warm, wet climate
  • Dense vegetation
• What are the abiotic components of an ecosystem?

  • Light
  • Soil
  • Water
  • Temperature
  • Climate
• How do biotic and abiotic components interact in an ecosystem?

  They constantly interact to maintain balance
• How are biotic elements further divided in an ecosystem?

  Into producers, consumers, and decomposers
• What are the key features of deserts?

  • Very dry
  • Sparse vegetation
• What are the abiotic components of an ecosystem?

  • Light
  • Soil
  • Water
  • Temperature
  • Climate
• What is the name of the eighth biome shown in the image?

  Tundra
• Why are abiotic factors important for biotic components?

  They provide necessary conditions for life
• What are the two main components of an ecosystem?

  Biotic and abiotic components
• What are the major types of terrestrial ecosystems based on climate and vegetation?

  Tropical rainforest, temperate forest, taiga, grasslands, deserts, mountains, tundra, Mediterranean
• What are the key features of the taiga ecosystem?

  • Cold climate
  • Evergreen needle trees
