What is macroalgae used for?
Macroalgae is a large type of algae that is mostly beneficial and is used mainly to fight nutrient levels and microalgae growth. It is most commonly found in refugiums in the sump area of a tank.
Is green algae a macroalgae?
Macroalgae (“seaweeds”) belong to either one of three groups of eukaryotic algae: the Rhodophyta (red algae), Chlorophyta (green algae), and Phaeophyceae (brown algae) or to the prokaryotic colony-forming Cyanobacteria/Cyanophyta (blue-green algae).

Can algae grow in the dark?
Injecting a gene from red blood cells gives microalgae the power to grow in the dark. Normally the microalgae rely on photosynthesis, but once reengineered, they can take up sugar for energy instead. But most microalgae can’t grow inside the dark tanks. …
What are red cod eaten by?
Adult Atlantic cod are only eaten by large sharks, but juveniles are eaten by a variety of medium-sized predators and are often even eaten by cannibalistic adults.
Is a cod fish a consumer?

Plants eaten by humans are called fruits and vegetables, and when they eat these plants, humans are primary consumers.
Why can’t a food chain start with a human being?
Food chains cannot start with human beings because we do not make our energy.
Who directly feed on producers are called?
Organisms which feed directly on producers are called Herbivores.
What are 4 primary consumers?
Primary consumers are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants). There are certain primary consumers that are called specialists because they only eat one type of producers.
What are 3 producers in the forest?
In the forest’s ecosystem, the trees, shrubs and moss are all producers. They turn water and sunlight into the energy they need to live and grow, through a process called photosynthesis.
Which is directly dependent on producers for living?
Answer Expert Verified All living organisms are inter depend on plants because plants take the food from sun by photosynthesis(auto trophs) and make them as food and animal which eat plants and indirectly take the sunlight and glucose (depend on the plant are called herbivores .
How humans and animals are directly or indirectly dependent on plants?
Humans and animals are dependent on plants directly or indirectly for food. Only plants are autotrophs i.e., they are capable of synthesizing their own food. Animals are heterotrophs i.e., they are incapable of synthesizing their own food. …
Are those that depends on producers directly or indirectly?
Organisms depend on the producers either directly or indirectly for their sustenance? These organisms which consume the food produced, either directly from producers or indirectly by feeding on other consumers are the consumers. Consumers can be classed variously as herbivores, carnivores, omnivores and parasites.
Which animals are indirectly dependent on plants?
Carnivores are indirectly dependent on plants for food.
- There are different types of animals in the food chain which are directly or indirectly dependent on the plants.
- Herbivores are directly dependent on plants for their food necessities.
How humans are dependent on plants and animals?
People depend on plants for food, clean air, water, fuel, clothing, and shelter. Nearly all food webs begin with plants, the primary producers. During photosynthesis, green plants use sunlight to change carbon dioxide from the air and water into simple sugars made of carbon, hydrogen, and oxygen.
Would a deer eat meat?
Many people may not know that deer, like some other herbivores, eat meat from time to time. It’s hard to imagine these creatures as steak-seeking predators, but deer will be quick to take advantage of a nutritious opportunity. In fact, deer can be a common danger for ground-nesting birds. …
How human beings are dependent on plants and animals?
Complete answer: People and animals are dependent on plants directly or indirectly for food. Just plants are autotrophs i.e., they are equipped for incorporating their food. Animals are heterotrophs i.e., they are unequipped for integrating their food. They depend on plants and different animals for food.
