Competition and Interdependence

• What does competition in an ecosystem refer to?

  Struggle for resources among organisms
• What is meant by interdependence in an ecosystem?

  Species relying on each other for survival
• What is the definition of a habitat?

  Environment where an organism lives
• What is the habitat of elephants mentioned in the video?

  The grasslands of Africa
• What is a population in ecological terms?

  Total number of same species in an area
• What is a community in an ecosystem?

  Populations of different species in a habitat
• What does the term biotic refer to?

  Living parts of the environment
• What does the term abiotic refer to?

  Non-living parts of the environment
• What is an ecosystem?

  Biotic and abiotic parts and their interactions
• What do living organisms require from their surroundings?

  A supply of materials like water
• Why do living organisms compete with each other?

  Resources are often in short supply
• What do plants compete for?

  Light, space, water, and mineral ions
• What do animals compete for?

  Food, water, mating partners, and territory
• What is interdependence in a community?

  Species relying on each other for resources
• What do lions eat in the ecosystem described?

  Animals such as zebras and gazelles
• How do zebras and gazelles obtain food?

  By eating grass and shrubs
• What role do some living organisms play in providing shelter?

  They offer protection from environmental factors
• How do plants depend on animals?

  For pollination and seed dispersal
• What happens if a species disappears from a community?

  It can affect the entire community
• What is a stable community?

  Populations of species remain fairly constant
• What does it mean for populations to be in balance?

  They coexist without overpopulation or extinction
• What abiotic resource is mentioned in the video?

  Water
• What are the key definitions related to ecosystems that should be learned?

  • Habitat: Environment where an organism lives
  • Population: Total number of same species in an area
  • Community: Populations of different species in a habitat
  • Biotic: Living parts of the environment
  • Abiotic: Non-living parts of the environment
  • Ecosystem: Biotic and abiotic parts and their interactions
• What resources do organisms compete for in ecosystems?

  • Plants: Light, space, water, mineral ions
  • Animals: Food, water, mating partners, territory
• What are the consequences of interdependence in ecosystems?

  • Species rely on each other for food and resources
  • Disappearance of one species affects the whole community
  • Example: Bees are crucial for plant pollination
