Exploring Mission Trails Ecosystem

What is an ecosystem?

• A type of plant found in Mission Trails

• A community of living organisms and their environment

• A geological feature in San Diego

• A type of animal species

Why is biodiversity important for an ecosystem?

• It makes the ecosystem look more colorful

• It helps the ecosystem adapt to changes and challenges

• It increases the number of invasive species

• It reduces the number of native species

Which of the following is a native species in the Mission Trails region?

• Argentine ant

• Yellow star-thistle

• California sagebrush

• Coastal cactus wren

How do invasive species affect native biodiversity?

• They help native species grow

• They compete with native species for resources

• They increase the number of native species

• They have no effect on native species

What is the role of decomposers in an ecosystem?

• They produce food for herbivores

• They break down dead organic matter

• They pollinate plants

• They compete with native species

Explain how pollinators and plants have a mutualistic relationship.

• Pollinators eat the plants, which helps them grow

• Pollinators transfer pollen, helping plants reproduce, while getting food

• Plants provide shelter for pollinators, which helps them survive

• Pollinators protect plants from invasive species

Why is it important to stay on designated paths when visiting Mission Trails?

• To avoid getting lost

• To protect native plants and animals from disturbance

• To see more wildlife

• To make the trails look neat

Describe how adaptations help organisms survive in their specific habitats.

• Adaptations make organisms more colorful

• Adaptations allow organisms to access resources like water during droughts

• Adaptations make organisms larger

• Adaptations help organisms migrate

What is a food chain?

• A series of organisms where energy is transferred from one to another

• A type of plant found in Mission Trails

• A geological feature in San Diego

• A type of animal species

How do riparian zones differ from chaparral areas in terms of habitat conditions?

• Riparian zones are dry, while chaparral areas are wet

• Riparian zones are rich in water, while chaparral areas have drought-resistant shrubs

• Both have the same conditions

• Chaparral areas are rich in water, while riparian zones are dry
