What type of consumer is a sea urchin?
Sea urchins are powerful primary consumers in kelp forests. These small herbivores eat dozens of kilograms (pounds) of giant kelp every day. Secondary consumers eat herbivores. They are at the third trophic level.
Where do yabbies fit in a food web?
The yabby and bacteria are decomposers. They live at the bottom of the water. They decompose dead-plants, they make food from things no other animal eats.
Are urchins decomposers?
Ocean decomposers have a variety of methods for gathering dead material to feed on. Echinoderms like sea urchins, sea stars and sea cucumbers hunt and eat live food, but they also move around and consume decaying organic matter that covers rocks and other surfaces.
Are sea otters decomposers?
The sea otter is a secondary consumer, an omnivore, and eats kelp (kelp is a kind of seaweed) and sea urchins. Some sea urchins eat dead animal matter which also can make them decomposers.
Are Boatmen decomposers?
All plants are producers. 2. Water boatmen eats algae and reeds. The yabbies are scavengers (decomposers), they eat all rotting plant and animal matter.
Does water ribbons have chlorophyll?
3. Algae, water ribbons, bulrushes and reeds contain chlorophyll. These are producer as they produce their own food by using light energy.
What is the food chain for the grasslands?
The grass, deer and tiger form a food chain (Figure 8.2). In this food chain, energy flows from the grass (producer) to the deer (primary consumer) to the tiger (secondary consumer). A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3).

What are the decomposers in the grasslands?
A: Decomposers found in temperate grasslands include insects, microorganisms and fungi. Small insects called arthropods live within the soil of many biomes, including grasslands. They not only decompose and shred organic material, but they also stimulate the growth of other decomposers such as fungi.
Are there any decomposers in the African savanna?
The (African Dung) Beetle (neateuchus proboscideus) is one of the very few decomposers that live in the African savanna grassland due to the many scavengers that live in the grassland biome.
How is the organic matter of the grasslands decomposed?
The organic matter of the grasslands is decomposed by the following matters. 1. Fungi ( Mucor, Rhizopus, Aspergillus ect.) 2. Bacteria ( some of the aerobic and anaerobic soli bacteria) 3. Earthworms 4. some Beetles 5. Flies present inthe grassland biome.
What are the producers in a grassland ecosystem?
Grasses, shrubs, trees, mosses, lichens, and cyanobacteria are some of the many producers found in a grassland ecosystem. When these plants die they provide energy for a host of insects, fungi and bacteria that live in and on the soil and feed on plant debris.
