Plants and Animals in the Environment

Believe it or not, plant/insect interaction is very much like the cold war and the accompanying arms race between the United States and the former Soviet Union . Bees and other insects help pollinate flowers. Earthworms aerate the soil Relationships between animals and plants are complicated. The food chain begins. Have students observe and record the behavior of animals (insects, spiders, birds a mutualistic relationship between the plant and its animal disperser. Many.

Hummingbirds and honeycreepers, for example, have distinctive beaks that have evolved to exploit flowers. Often, a beak may be so specialized that it is only effective on a small group of flowers. The pollinators, in turn, have evolved to take advantage of the flowers.

A successful pollinator typically has good color vision, a good memory for finding flowers, and a proboscis, or tongue, for attaining nectar. Animal pollination has obvious advantages for plants. Many pollinators cover great distances, which insures genetic diversity through outcrossing, or the transfer of pollen to unrelated individuals.

The pollinator benefits as well by gaining access to a source of food. The relationship of pollinator plant is an example of mutualism.

Imperiled Pollinators All is not well in the realm of pollinators. The age-old relationships between plants and pollinators is threatened, especially in urbanized and agricultural regions. Habitat destruction and fragmentation, pesticide abuse, and disease all have taken their toll on pollinators.

As more land is cleared for human habitation, bees, butterflies, bats, and birds are left homeless. Our gardens offer little to sustain them. They need a constant source of nectar and pollen throughout the entire season.

The few flowering plants most people grow will not suffice. A related problem is fragmentation of plant communities. Plants must be pollinated in order to set seed for the next generation. Without pollinators, no seed is set and the plants eventually die out, leading to local extinction. Isolated patches of forest, grassland, or desert are particularly vulnerable.

A small patch may not sustain enough pollinators, or may be too far from other patches for pollinators to travel. As a result, plants do not reproduce. Pesticides have also reduced pollinator populations. Bees are often killed by chemicals applied to eliminate other pests. Honeybees are being destroyed by diseases and parasitic mites.

The crisis is not just affecting native ecosystems. Fruit trees and many other food crops depend on pollination for production. We stand to lose over three quarters of our edible crops if we lose pollinators. What can be done? Encourage pollinators by planting a diverse mixture of adult and larval food plants in your garden.

Erect bat and bird houses, as well as bee hives.

Reduce or eliminate pesticide use. Help restore native plant communities not only in your yard, but also in parks and along roadways, and connect them through corridors to preserves and other natural areas.

Plants and Their Dispersers No two plants can occupy the same spot.

In order to have room to grow, seeds must be dispersed away from the parent plant. Seed dispersal is accomplished by a variety of means, including wind, water, and animals. Animal dispersal is accomplished by two different methods: Animals consume a wide variety of fruits, and in so doing disperse the seeds in their droppings. Many seeds benefit not only from the dispersal, but the trip through the intestine as well. Digestive acids scarify seeds, helping them to break out of thick seed coats.

Some seeds are armed with hooks and barbs that enable them to lodge in the fur of animals that brush past them.


Beggar's ticks and bur marigold are two examples. Eventually, the seeds are rubbed or scratched off, and may find a suitable spot on which to germinate and grow.

People are important for dispersing plants, too. The common weed plantain was called "white man's footsteps" by Native Americans because wherever settlers walked, the plantain came in the mud on their shoes. Some Animals and the Plants They Disperse Ants - Many wildflowers, such as trilliums, bloodroot, violets Birds - Fleshy fruits and grains, such as baneberry, viburnums, mountain ash Clark's Nutcracker - Whitebark pine Mammals - Fruits, grains, nuts, berries Squirrel - Nuts, such as those of oaks, hickories, pines Fox - Berries, such as blackberry, grapes Humans - Weeds such as plantain, dandelion, lamb's-quarters Reptiles - Fleshy fruits, especially berries such as strawberry, groundcherry, jack-in-the-pulpit Mutualism Mutualism is an obligate interaction between organisms that requires contributions from both organisms and in which both benefit.

Animals can be used for asistance when compensating for disabilities and to perform work or provide recreation. Humans can control and alter the environment. Farming by humans increases the amount of food by encouraging plants to grow by cultivation.

Humans can also control the environment to compensate for disabilities. Humans can permanently damage the environment. The resources and minerals that are removed from the ground are not renewable. Materials Pictures of plants and animals Science Journals Procedure 1.

At the outset students discuss the different habitats or ecosystems in the area of the school and in New Jersey. Among others, we have the forest habitat in northwest New Jersey, the Pine Barrens, the shore, and urban environments and habitats including parks. Students work in groups or individually. They select a plant or an animal that is common in the community and study it.

Plant/Animal Relationships

They write about it in their Science Journals. Students combine their individual studies to determine the relationships between the different plants and animals they have studied. Students make presentations to the class about the plants and animals they studied. In their Science Jorunals, all students write about the plants and animals in the environment.
