Shipworms Shipworms are not worms. Think you know what they are?
Shipworms Shipworms are actually clams.
Shipworms Shipworms get their name from their long, narrow, cylindrical bodies.
Shipworms A closer look at the creature reveals a shell at its front. This shell has two halves with a gap in between, like a clamshell.
Shipworms These termites of the sea have an organ full of bacteria that digest wood. They eat sawdust which they produce as they scrape through the wood.
Shipworms The bacteria take nitrogen from the water and convert it to protein for the worm. The bacteria, in return, get nutrients form their host.
Shipworms Shipworms begin life in the plankton. When it finds a piece of wood, it uses its shell to eat its way into the wood.
Shipworms As the shipworm grows, so does the burrow. Some worms can be as long as six feet.
Shipworms Their breathing siphons remain at the surface of the wood as they grow to obtain their needed oxygen.
Shipworms Once a shipworm claims a home, its stuck there for life.
Shipworms Even when removed intact and uninjured, the shipworms are unable to dig new burrows!
Shipworms Shipworms play an important role in reducing the amount of driftwood in the worlds oceans.
Biogeochemical Cycles. The movement of nutrients from the non- living world into living organisms, and then back again.
Clams come in many colors, including shades of brown, red-brown, yellow and cream They have shells consisting of two halves The halves are connected at.
Biogeochemical Cycles. What is a cycle? Some are simple Some are complex.
ECOSYSTEMS OF THE OCEAN
Ecology Part 6 Carbon & Nitrogen Cycles R. Martinez, 2012.
Atmospheric Movement in Weather Change. Weather The short-term (a few hours or days) condition of the atmosphere at a given location. Water and air.
Sustainable Ecosystems. Nutrient Cycles and Energy Flow All life on earth requires water and food. Water provides the liquid component that makes up cells.
Nutrient Cycles -Academic Water Cycle (pg.) 1. The movement of water between the oceans, atmosphere, land and living things is the water cycle. 2. Evaporation.

Mollusks Chapter 10 Section 1. Characteristics of Mollusks Clams, oysters, scallops, snails, squids Invertebrates with soft, unsegmented bodies Often.
Dead Zones in the Ocean. What is the Nitrogen Cycle? The nitrogen cycle is the process in which nitrogen circulates among the air, soil, water,
A killer whale can hold its breath for up to 15 minutes Also it can eat up to 10% of there body weight.

The Non-living Environment Obj. 4a. The features of the environment that are or once were alive are called biotic factors (biotic means “living”) Biotic.
