Whatever floats by. sessile animals are stuck in place, and can't move. They're usually aquatic animals. Hope this helps! :)
The brain represents 2% of the total body weight for a human. But it uses 20% of the total oxygen and calories absorbed by the body (so ten times more than its weight ratio) it proves that it is an important organ that need a lot of energy.
The brain is the seat of higher functions (cognitive functions, senses, nervous responses) and vegetative functions. It is, therefore, an essential organ that regulates all vital functions. Like a central unit in a desk computer, the brain receives information from the entire human body via afferent nerves, integrates and analyzes them, and responds by emitting new signals that descend to the parts of the body concerned by the efferent nerves.
1.Burning fossil fuels
When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere.
Australians are big producers of CO2 pollution compared to the rest of the world. Our level of CO2 pollution per person is nearly double the average of other developed nations and more than four times the world average.
Electricity generation is the main cause of carbon pollution in Australia as 73% of our electricity comes from burning coal and 13% from burning gas. The remaining 14% comes from renewable energy sources such as hydro, solar and wind, which do not emit carbon.
Reducing the amount of electricity generated from coal and gas, and increasing the amount of electricity from clean, renewable energy sources like solar and wind, means less carbon pollution is emitted. This is one of the main ways we can address global warming.
Deforestation
Plants play an important role in regulating the climate because they absorb carbon dioxide from the air and release oxygen back into it. Forests and bushland act as carbon sinks and are a valuable means of keeping global warming to 1.5°C.
But humans clear vast areas of vegetation around the world for farming, urban and infrastructure development or to sell tree products such as timber and palm oil. When vegetation is removed or burnt, the stored carbon is released back into the atmosphere as CO2, contributing to global warming. Up to one-fifth of global greenhouse gas pollution comes from deforestation and forest degradation.Global warming, population growth, and natural resources for food production. PIP: Destruction of forests and the considerable burning of fossil fuels is directly causing the level of carbon dioxide and other greenhouse gases including methane, carbon monoxide, and nitrous oxide in the atmosphere to rise.

Answer:
Physical characteristics: Freshwater sponges are crustlike, branched, or clumped. The texture is fragile and soft, and the color is whitish or green. Freshwater sponges have irregularly scattered and barely visible water-exit holes.
Geographic range: Freshwater sponges live in North America, Europe, and Asia.
Habitat: Freshwater sponges live in standing and running fresh water.
Diet: Freshwater sponges are filter feeders.
Behavior and reproduction: Scientists know little about how freshwater sponges behave. These sponges reproduce asexually by forming buds in late summer that spend the winter in a dormant state and emerge from the adult in the spring. Freshwater sponges reproduce sexually during the summer, giving birth to live larvae.
