- Producers and consumers
Energy flows directionally through ecosystems, entering as sunlight or inorganic molecules for chemoautotrophs and leaving as heat during energy transformation between trophic levels. Rather than flowing through an ecosystem, the matter that makes up organisms is conserved and recycled. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in the cycling of elements on Earth. The six aforementioned elements are used by organisms in a variety of ways. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins.

Published by Eleanore Newton Modified over 5 years ago. Primary producers are the first producers of energy-rich compounds that are later used by other organisms. Organisms need energy for growth, reproduction, and metabolic processes. No organism can create energy—organisms can only use energy from other sources.
For most life on Earth, sunlight is the ultimate energy source. For some organisms, however, chemical energy stored in inorganic chemical compounds serves as the ultimate energy source for life processes.
These organisms are called autotrophs. Autotrophs are also called primary producers. Primary producers store energy in forms that make it available to other organisms that eat them, and are therefore essential to the flow of energy through the biosphere. For example, plants obtain energy from sunlight and turn it into nutrients that can be eaten and used for energy by animals such as a caterpillar. Photosynthesis captures light energy and uses it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates.
This process adds oxygen to the atmosphere and removes carbon dioxide. Algae fill that role in freshwater ecosystems and the sunlit upper ocean. Photosynthetic bacteria, most commonly cyanobacteria, are important primary producers in tidal flats and salt marshes.
Deep-sea ecosystems depend on primary producers that harness chemical energy from inorganic molecules such as hydrogen sulfide. The use of chemical energy to produce carbohydrates is called chemosynthesis. Organisms that rely on other organisms for energy and nutrients are called consumers. Organisms that must acquire energy from other organisms by ingesting in some way are known as heterotrophs.
Heterotrophs are also called consumers. Carnivores kill and eat other animals, and include snakes, dogs, cats, and this giant river otter. Catching and killing prey can be difficult and requires energy, but meat is rich in nutrients and energy and is easy to digest. Scavengers, like a king vulture, are animals that consume the carcasses of other animals that have been killed by predators or have died of other causes.
Decomposers, such as bacteria and fungi, feed by chemically breaking down organic matter. The decay caused by decomposers is part of the process that produces detritus—small pieces of dead and decaying plant and animal remains. Common herbivores include cows, caterpillars, and deer. Omnivores are animals whose diets naturally include a variety of different foods that usually include both plants and animals. Humans, bears, and pigs are omnivores. Detritivores, like giant earthworms, feed on detritus particles, often chewing or grinding them into smaller pieces.
Detritivores commonly digest decomposers that live on, and in, detritus particles. For example, herbivores that eat different plant parts often differ greatly in the ways they obtain and digest their food. In addition, organisms in nature often do not stay inside the categories we put them in.
For example, some carnivores will scavenge if they get the chance. Many aquatic animals eat a mixture of algae, bits of animal carcasses, and detritus particles.
It is important to expand upon consumer categories by discussing the way that energy and nutrients move through ecosystems. Producers Sunlight is the primary source of energy source for life on earth. Plants, algae, and some bacteria. Energy Flow. Sunlight is the MAIN source of energy for all life on Earth Only plants, some algae, and certain bacteria can capture energy from the sun.

River ecosystems are flowing waters that drain the landscape, and include the biotic living interactions amongst plants, animals and micro-organisms, as well as abiotic nonliving physical and chemical interactions of its many parts. River ecosystems are prime examples of lotic ecosystems.
Producers and consumers
Ecosystems can be small, such as the tide pools found near the rocky shores of many oceans, or large, such as those found in the tropical rainforest of the Amazon in Brazil Figure 1. There are three broad categories of ecosystems based on their general environment: freshwater, marine, and terrestrial. Within these three categories are individual ecosystem types based on the environmental habitat and organisms present. Freshwater ecosystems are the least common, occurring on only 1. These systems comprise lakes, rivers, streams, and springs; they are quite diverse and support a variety of animals, plants, fungi, protists and prokaryotes. Shallow ocean ecosystems include extremely biodiverse coral reef ecosystems.
Text 6. Ecological Problems. Ecology is a science which studies the relationship between all forms of life on our planet and the environment. There are also some alternatives to cleaners and pesticides, soda, for example. There is an answer, and it lies in the principles of ecology. Let's take a look.
