Unlike in aquatic ecosystems, the eggs may sit around longer in terrestrial ones. A consumer is any organism that gets its energy from eating, or consuming, another organism. Familiar images of consumers include lions eating gazelles, and birds, like this roadrunner, munching on a lizard. These animals are called carnivores because they eat meat. Other consumers are called herbivores. They eat plants and plant-like organisms. Herbivores could include deer and giraffes in terrestrial ecosystems, ducks and some fish in freshwater ecosystems, and some fish and manatees in ocean ecosystems. A producer is an organism that makes food for itself through the process of photosynthesis. This process takes energy from the sun, combines it with water and carbon dioxide, and creates sugars. Many types of plants live in all ecosystems. Terrestrial producers include trees, rose bushes, and grass. Freshwater producers include diatoms, pondweed, and reeds, and ocean producers include salt grasses, seaweeds, and diatoms. Producers are considered the bottom of the food chain. This means that all of the upper levels (the consumers) rely on the producers for their energy. Take for example a top land predator, the polar bear. In the Arctic, the waters are loaded with microscopic algae, making tons of food from the sun. This algae is eaten by small fish. Larger fish eat the small fish, which are then eaten by leopard seals. When a polar bear eats the leopard seal, it is, indirectly, getting the energy from the sun. A great producer/consumer relationship. In terrestrial ecosystems there are many examples of producer/consumer relationships. In the forest, many species of plants produce seeds. Mice eat these seeds (producer/consumer relationship #1). A snake might eat the mouse, which will indirectly give it some of the sun’s energy (producer/consumer relationship #2). Finally, a snowy owl might eat the snake. Again, it will indirectly get the sun’s energy (______). Whatever the consumer is and whichever ecosystem it lives in, it can get direct or indirect energy from the producers. Predators are a special type of consumer. In order to be a predator, one must hunt and kill its food, or prey. In the oceans, one of the top predators is the Great White Shark. This fish is designed to eat, having rows and rows of teeth. It will hunt down and eat seals, large fish, squid, and even injured whales. The great white shark sits at the top of the food web and is a top consumer. In terrestrial ecosystems, predators include lions, snakes, hawks, and even the shrew. Each of these animals hunts down prey, kills it, and eats it. Freshwater ecosystems can also have predators. Many birds eat the fish and shellfish that live in freshwater lakes and ponds. They swoop down out of the air and snatch them up to eat them. Freshwater, marine, and terrestrial ecosystems all have organisms that are always interacting with each other. Some of these relationships are very one sided (as in the predator/prey and parasite/host), but they are essential for the survival of all living things. As energy is transmitted through the food web, some organisms can even play multiple roles. There are times when an animal, like a snake, may be a predator, but then when an owl eats it, it becomes prey. All these relationships keep ecosystems in balance and energy being transferred.

The will absorb nutrients that the host should get, and use them for its own metabolism. Over time, the host will weaken because of the lack of nutrition. At this point, the needs to release its eggs into the environment so that it can carry on. In freshwater and marine ecosystems, water is used to transport the eggs to the next host. The eggs float around until another organism accidentally consumes them. Reproduction in a terrestrial ecosystem is a bit more difficult. The eggs are often consumed when a grazing animal takes a drink from an infected pond or other water source.
