What is the definition of an ecosystem?
An ecosystem is a collection of non-living materials in a region.
An ecosystem is a group of unrelated species living in isolation.
An ecosystem is a community of living organisms and their physical environment interacting as a system.
An ecosystem is a network of artificial structures and machines.
Which of the following is a component of an ecosystem?
Plants
Waterfalls
Clouds
Rocks
What are biotic factors in an ecosystem?
Biotic factors are the non-living elements of an ecosystem.
Biotic factors are the chemical substances in an ecosystem.
Biotic factors are the living components of an ecosystem.
Biotic factors refer to the physical environment of an ecosystem.
Give an example of an abiotic factor.
Rainfall
Soil nutrients
Sunlight
Temperature variations
What type of ecosystem is characterized by high rainfall and diverse species?
Rainforest
Savanna
Tundra
Desert
Which ecosystem is known for its coral reefs?
Temperate forest ecosystem
Desert ecosystem
Freshwater ecosystem
Marine ecosystem
What role do mangrove swamps play in coastal ecosystems?
Mangrove swamps are mainly used for agricultural purposes in coastal regions.
Mangrove swamps primarily serve as tourist attractions in coastal areas.
Mangrove swamps act as breeding grounds for freshwater fish species.
Mangrove swamps play a vital role in coastal ecosystems by providing habitat, protecting shorelines, filtering water, and sequestering carbon.
Name a biotic factor found in a tropical rainforest.
river
coconut tree
mountain goat
jaguar
What is the importance of abiotic factors in an ecosystem?
Abiotic factors are essential as they shape the environment, influence biodiversity, and support life processes.
Abiotic factors are solely responsible for climate change effects.
Abiotic factors only affect animal behavior in ecosystems.
Abiotic factors are irrelevant to ecosystem dynamics.
How do biotic and abiotic factors interact in an ecosystem?
Biotic factors do not influence the physical environment.
Both factors operate independently without interaction.
Biotic and abiotic factors interact by influencing each other's survival, growth, and behavior in an ecosystem.
Abiotic factors only affect the climate in an ecosystem.
What type of organisms are typically found in coral reefs?
Corals, fish, mollusks, crustaceans, sponges, and algae.
Mammals, birds, reptiles, and amphibians.
Bacteria, fungi, viruses, and protozoa.
Sea turtles, sea urchins, jellyfish, and anemones.
Describe one way that abiotic factors can affect biotic factors.
Soil pH can determine the height of plants.
Temperature can affect the metabolic rates of organisms.
Humidity can influence the color of leaves.
Wind speed can change the shape of animal habitats.
What is a key characteristic of mangrove swamps?
Desert flora
Cold-weather trees
Salt-tolerant vegetation
Freshwater plants
How do tropical rainforests contribute to the global ecosystem?
Tropical rainforests are mainly responsible for ocean currents.
Tropical rainforests primarily serve as agricultural land.
Tropical rainforests contribute to urban development and infrastructure.
Tropical rainforests contribute to the global ecosystem by acting as carbon sinks, producing oxygen, supporting biodiversity, regulating climate, and maintaining the water cycle.
What are some threats to coral reef ecosystems?
Climate change, pollution, overfishing, habitat destruction
Invasive species, ocean acidification, coastal development
Natural disasters, sea level rise, tourism impact
Freshwater influx, sedimentation, marine traffic
What do we call a place where living and non-living organisms interact in the same environment?
Life cycle
Ecosystem
Food Chain
What are the two components of an ecosystem?
Microorganisms
Biotic and Abiotic
Living things and non living things
