Niveles de organización de los ecosistemas

What is a biome?

• A biome is a type of weather pattern

• A biome is a small geographical area with no distinctive plant and animal groups

• A biome is a man-made structure

• A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment.

Give an example of a biotic interaction in an ecosystem.

• Trees photosynthesizing with sunlight

• Rocks eroding due to weathering

• Worms burrowing in soil

• Bees pollinating flowers

Explain the role of abiotic factors in an ecosystem.

• Abiotic factors are only related to living organisms in an ecosystem

• Abiotic factors only affect one species in an ecosystem

• Abiotic factors have no impact on ecosystems

• Abiotic factors influence the environment and living organisms in an ecosystem by providing essential resources and setting physical conditions that affect the ecosystem's overall health and biodiversity.

Name two types of biomes and describe their characteristics.

• Temperate forest and chaparral

• Taiga and grassland

• Tropical rainforest and desert

• Arctic tundra and savanna

How do biotic interactions contribute to the stability of an ecosystem?

• Biotic interactions promote biodiversity, regulate population sizes, enhance nutrient cycling, and provide ecosystem services.

• Biotic interactions always result in the extinction of species

• Biotic interactions only lead to competition and instability in ecosystems

• Biotic interactions have no impact on ecosystem stability

Discuss the impact of abiotic factors on the distribution of organisms in an ecosystem.

• Abiotic factors have no impact on the distribution of organisms

• Abiotic factors directly influence the distribution of organisms by affecting their survival and growth based on their specific tolerances.

• Organisms can adapt to any abiotic factor in an ecosystem

• Abiotic factors only affect the distribution of plants, not animals

What are the primary producers in an ecosystem and why are they important?

• Primary producers are unimportant as they do not contribute to the ecosystem

• Primary producers are secondary consumers in the food chain

• Primary producers are only found in aquatic ecosystems

• Primary producers are important because they form the base of the food chain by converting sunlight into energy.

Describe a predator-prey relationship in an ecosystem.

• The predator and prey in an ecosystem do not interact with each other.

• Predator and prey in an ecosystem have a symbiotic relationship.

• In a predator-prey relationship, the predator hunts and consumes the prey as a source of food.

• In a predator-prey relationship, the prey hunts and consumes the predator.

How do abiotic factors like temperature and rainfall affect the biodiversity of an ecosystem?

• Temperature and rainfall can limit biodiversity by affecting the survival and reproduction of different species in an ecosystem.

• Extreme temperature and rainfall always increase biodiversity

• Biodiversity is only influenced by biotic factors

• Temperature and rainfall have no impact on biodiversity

Explain the concept of a food chain and provide an example from a specific biome.

• In the Arctic biome, a food chain includes polar bears eating berries, which are then consumed by penguins, and finally, wolves eat the penguins.

• In the ocean biome, a food chain involves seaweed being eaten by sharks, which are then consumed by jellyfish, and finally, dolphins eat the jellyfish.

• In the tropical rainforest biome, an example of a food chain could be: plants (producers) are eaten by insects (primary consumers), which are then consumed by frogs (secondary consumers), and finally, snakes (tertiary consumers) eat the frogs.

• In the desert biome, a food chain consists of lions eating grass, which is then consumed by rabbits, and finally, eagles eat the rabbits.
