Animals Dispersing Seeds

A student wants to create a model to show an animal's role in dispersing seeds. Which of the following scenarios should the student use for the model?

• A hummingbird drinks nectar from several different flowers.

• A bee lands on a tulip and pollen sticks to its legs.

• A red fox eats berries off of a brush in the forest.

• The wind blows the seed off of a dandelion.

A student is developing a model for how plants are pollinated. Which of the following should be included in the student's model?

• Pets eat flowers in the garden.

• Pollen sticks to the insect's legs.

• An insect drinks nectar from a plant.

• The wind blows pollen around the sky.

Students are tasked with representing the animal's role in dispersing seeds. Student's model ideas are documented.

Which student would represent the situation best?

• Student 1

• Student 2

• Student 3

• Student 4

A student creates the following model to show an animal's role in dispersing seeds.

Which of the following conclusions could be drawn from the model?

• A new plant can grow after the rabbit and birds release seeds in their droppings.

• A new plant can grow after the moving of seeds from wind and rain.

• A new plant will take over the area the original plant was located.

• A new plant can grow after seeds are stuck to the birds feathers.

A student creates the following model to show pollination in flowering plants.

What is the role, purpose, of the bee?

• The bee eats nectar from the plants, so when it goes from plant to plant it carries pollen with it.

• The bee eats nectar from the plants, so when it goes from plant to plant, it carries nectar with it.

• The bee lives in the flowers, which allow the plants to release its pollen to another flower.

• The bee is not involved in pollination, but it shows an animal that eats from the flower.

A student develops the following model to show the pollination in plants.

What is a problem with the model created?

• It does not show how plants are pollinated.

• The model accurately describes pollination.

• It should show a start to an end rather than a circular flow chart.

• The model should be compared to the life cycle of animals in the area.

Which scenario best illustrates an animal's role in seed dispersal?

• A squirrel buries nuts in the ground, which later sprout into new plants.

• A bird builds a nest using twigs and leaves.

• A cat chases insects around a garden.

• Rain washes seeds into a new location.

What role does an animal play in the dispersal of seeds according to the student's model?

• The animal transports seeds stuck to its fur to different locations.

• The animal consumes the seeds, which are later destroyed in its digestive system.

• The animal observes the seeds but does not interact with them.

• The animal plants seeds intentionally to grow more food sources.
