Plants and Animals in the Environment
Originally Answered: What is the relationship between plants and animals? Relation between plants and animals depends on their life cycle, animals need. Over the past two decades, numerous field and experimental studies on the ecology and evolution of animal and plant interactions have been reported by. relationships that occur between plants and animals. (mutualism, commensalism, predation and parasitism). ❀ generate hypotheses about plant and animal.
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.
THE ECOSYSTEM: INTERRELATIONSHIPS BETWEEN
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.
On the relationships between plants 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.
There are many examples in nature. Pollination and dispersal, discussed above, are mutualistic because both plant and pollinator or disperser benefit from the relationship. The relationship between mycorrhizal fungi and many higher plants is another common example of mutualism.
The bodies of the fungi, called hyphae, live on or in the tissues of plants, and make nutrients available for the plants to absorb. The plants provide the fungi with amino acids and other complex compounds. One of the most celebrated examples is the orchids.Symbiosis: Mutualism, Commensalism, and Parasitism
Whereas some plants may support as many as different fungi, orchids have quite specific mycorrhizal associations. Different plant communities have different mycorrhizal associations.

The microflora of a grassland is different from that of a forest. These differences, at least in part, may influence the distribution of plant communities. A group of organisms of the same kind living in a given area Natural Community: Populations of different plant and animal species interacting among themselves in an area. The specific physical location where a particular organism lives or is adapted to live in a community. The single abiotic factor most lacking in a particular environment is termed a Limiting Factor.
The variation in physical factors that a population can withstand and continue to thrive in an environment is termed Range of Tolerance.
Green plants that carry on photosynthesis. Producers are termed auto-trophs because they are self-nourished — they do not depend on other species to feed. During photosynthesis, plants capture light energy with their chlorophyll and use it to convert carbon dioxide and moisture absorbed from air into sugar chemical energy. Oxygen is released as a by-product Every major ecosystem has its particular green plants that carry on photosynthesis and release chemical energy carbohydrates, protein etc.
Species that feed directly on producers plant-eating species. They are also called Herbivores. Species that feed on primary consumers.

Secondary and higher order consumers are called Carnivores. Tertiary and higher level Consumers: Species that obtain their nourishment by eating other meat-eating species. Species that obtain their nourishment from eating both plants and animal species.
Also called Omnivores 3.
