How do sponges feed?
Sponges are filter feeders that sift microscopic particles of food from the water.
How do sponges internal transport.
Water is pumped into the sponge by pore cells then release out of the osculum.
How do sponges Excretion?
Water carries away metabolic wastes produced by cellular respiration (such as ammonia).
How do sponges Respiration?
Water passs throught the cell wall and sponge cells remove oxygen and gives off carbon dioxide.
How do sponges Reproduce?
Sponges reproduce sexually and asexually. It can regenerate. Sperm are released in the water and swim until it reaches an egg in the sponge.
Sponges protect themselves by...?
Giving of toxins.
