A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3). In a freshwater aquatic ecosystem like a pond, the organisms in the food chain include algae, small animals, insects and their larvae, small fish, big fish and a fish-eating or animal (Figure 8.4).

Read more...An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, without natural predators.. Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels.Food chains are often far shorter on land, usually limited to being secondary consumers – for example, wolves prey mostly upon large ...

Read more...If one species goes extinct, the entire food chain can become endangered causing other species to become extinct. Equilibrium As the number of carnivores in a community increases, they eat more and more of the herbivores, decreasing the herbivore population. It then becomes harder and harder for the carnivores to find herbivores to eat, and the ...
Read more...Consequently, species' responses to habitat destruction vary as other species become extinct. Our results reiterate the importance of the interplay between bottom-up and top-down control in trophically linked communities, and highlight the complex responses occurring in even a simple food chain.
Read more...Keystone Species: In some food webs, there is one critical "keystone species" upon which the entire system depends. In the same way that an arch collapses when the keystone is removed, an entire food chain can collapse if there is a decline in a keystone species.

Every living thing—from one-celled algae to giant blue whales—needs food to survive.Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight. A rabbit eats the grass.
Read more...Feb 01, 2019· Aquatic food webs. Food webs describe who eats whom in an ecological community. Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly. Phytoplankton and algae form the bases of aquatic food webs.
Read more...Mar 26, 2019· Losing apex species has multiple effects. Eliminating the large predators at the top of the food chain, the "apex species," may be humans' most serious impact on nature, according to one study. These large species are more vulnerable because they live longer, reproduce more slowly, have small populations, and need more food and a greater ...
Read more...Apr 16, 2015· The abiotic environment has strong influences on the growth, survival, behavior, and ecology of aquatic organisms. Biotic interactions and species life histories interact with abiotic factors to structure the food web. One measure of food-web structure is food-chain length. Several hypotheses predict a linear relationship between one environmental variable (e.g., disturbance or ecosystem size ...
Read more...Food chain is a linear sequence of organisms which starts from producer organisms and ends with decomposer species. Food web is a connection of multiple food chains. Food chain follows a single path whereas food web follows multiple paths. From the food chain, we get to know how organisms are connected with each other.
Read more...A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. Let's look at the parts of a typical food chain, starting from the bottom—the producers—and moving upward. At the base of the food chain lie the primary producers.

In a group, combine your food chain with the food chains of your classmates who focused on the same the coastal habitat. This food web should include at least 10 organisms.
Read more...A food chain is a chain that shows the relationship between species based upon their feeding. A food chain often begins with a plant because it is able to make its own food. This type of link on the food chain is referred to as a producer. The first animal to eat the producer is referred to as the primary consumer. An animal that eats the primary consumer is referred to as a secondary consumer.
Read more...The phrase 'food chain' is a way of indicating how energy moves through an ecosystem from the primary producer the green plants to the final consumer the decomposers. Types of Food Chains. Food chain can be classified into. Grazing food chain. This is the food chain which begins with the plants as primary producers and ends with tertiary ...
