What is an adaptation for organisms living in the upper intertidal zone?
They are well camouflaged so that they can blend in and hide from predators during low tide. What is an adaptation for organisms living in the upper intertidal zone? They must be adapted for being out of water for extended periods of time.
What organisms live between the sediment particles of a sandy beach?
Meiofauna are small organisms that live between sediment particles on sandy beaches.
Which of the following organisms are sessile?
Sessile animals such as sponges, corals, and anemones attach themselves to the bottom or substrate. This sessile lifestyle is advantageous to these organisms, because they do not have to expend large amounts of energy to move through the water to get food.
Which group of organisms are likely to live in the low tide zone?
Intertidal zones of rocky shorelines host sea stars, snails, seaweed, algae, and crabs. Barnacles, mussels, and kelps can survive in this environment by anchoring themselves to the rocks. Barnacles and mussels can also hold seawater in their closed shells to keep from drying out during low tide.
Which consumers live in the intertidal zone?
Types of Consumers Found at Intertidal Zones When the tide is in, littoral organisms are preyed upon by sea animals (like fish). When the tide is out, they are preyed upon by land animals, like foxes and people. Birds (like gulls) and marine mammals (like walruses) also prey on intertidal organisms extensively.
What types of plants live in the intertidal zone?
Some of the plants that inhabit the intertidal zone are seagrass, dead man's fingers, nori, the seagrape tree, and eelgrass. Some of the plants that live in the intertidal zone have special adaptations for living in such a changing area.
What is a challenge that organisms living in an intertidal zone face that other aquatic organisms normally do not face?
What is a challenge that organisms living in an intertidal zone face that other aquatic organisms normally do not face? Competitive exclusion says that two species trying to occupy the same niche in the same ecosystem will not be able to do so indefinitely, one species ultimately outcompeting the other.
Which of the following deep water fish was original called the Slimehead and is now on the Seafood Watch list of fish to avoid purchasing?
Roughies, previously known by the unappetizing name of slimeheads, are deepwater reef fish that appeared in the New Zealand market in the early 1980s. They are white, flaky, and delicious, and rapidly ascended to the top of fish counters and menus in America and Europe.

What is sessile form?
In biology, it means to stay in one place on the ground. It is the opposite of motile. It is mostly used for marine and freshwater species. They often have larvae which are motile, float or swim, and adult forms which are stationary. Many sessile forms can move from place if they need to.
What is a primary consumer?
Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.
Are zooplankton primary consumers?
The zooplankton community is composed of both primary consumers, which eat free-floating algae, and secondary consumers, which feed on other zooplankton.
Which is one of the ecosystems found in intertidal zones?
Intertidal zones have either rocky shore ecosystems or sandy shore ecosystems. Sandy shore ecosystems support many burrowing invertebrates, while rocky shores support organisms like bivalves, marine snails, sea anemones, and sea stars.
Which of the following deep water fish was originally called the toothfish?
The Chileans were the first to market toothfish commercially in the United States, earning it the name Chilean sea bass, although it is really not a bass and it is not always caught in Chilean waters. It is a different species type than the sea bass caught in U.S. waters.
Why is orange roughy called Slimehead?
Orange roughy (Hoplostethus atlanticus) , deep ocean fish that were once known as "slimeheads" because of the mucous-producing canals on their heads, grow and mature at a sluggish rate compared to most shallow water fish. They don't reproduce until they are at least 20 years old and can reportedly live to be 149.
Are plants sessile?
Plants are sessile organisms that are permanently restricted to their site of germination. To compensate for their lack of mobility, plants evolved unique mechanisms enabling them to rapidly react to ever changing environmental conditions and flexibly adapt their postembryonic developmental program.
Why are all plants sessile?
Because plants are “rooted” to the place where they germinate, they don't move. Indeed, it's become almost a cliche to describe plants as displaying a “sessile life-style”, especially when contrasting them to animals.
What is sessile quizlet?
What does sessile mean? an organism that is fixed to one place; immobile.
Is the primary producer?
Autotrophs or primary producers are organisms that acquire their energy from sunlight and materials from nonliving sources. Algae, higher plants, and some bacteria and protists are important autotrophs in running waters. Heterotrophs obtain energy and materials by consuming living or dead organic matter.
Who are called primary producers?
Green plants and certain bacteria are able to convert inorganic matter into biomass using energy from solar radiation or chemical energy. They are the first link in the food chain and are therefore called the primary producers (autotrophs).
Is plankton a primary producer?
They are what is known as primary producers of the ocean—the organisms that form the base of the food chain. Because they need light, phytoplankton live near the surface, where enough sunlight can penetrate to power photosynthesis.
Is zooplankton a primary producer?
Phytoplankton are the primary consumers of the ocean; Zooplankton are the primary producers of the ocean.
Which ocean communities or ecosystems are found in the intertidal zone quizlet?
The Intertidal Zone is where the land meets the sea. It is the area between high tide and low tide. Intertidal communities can be found on sandy beaches, in bays and estuaries, and along rocky shorelines.
Which of the following deep water fish was originally called the Slimehead and is now on the seafood Watch list of fish to avoid purchasing?
Hoplostethus atlanticus. Also called the slimehead, deep sea perch or red roughy, the orange roughy is a sedentary fish that dwells in deep cold waters.
When did the industrial fishing fleets first target the Patagonian toothfish?
Patagonian toothfish were first described in 1898 (Smitt, 1898), but interest in the species was limited until toothfish were caught as a by-catch in trawl fisheries off the South American coasts.
Are rockfish fishy?
The dish is not heavy (it's oven fried and not deep fried) and it's not fishy tasting because rockfish is so mild. It's fairly mess-free because it's cooked in the oven and not on a stovetop, and the final dish is firm but tender, flakey but crispy, light but indulgent.
What fish is red?
The red drum (Sciaenops ocellatus), also known as redfish, channel bass, puppy drum, spottail bass, or simply red, is a game fish found in the Atlantic Ocean from Massachusetts to Florida and in the Gulf of Mexico from Florida to northern Mexico. It is the only species in the genus Sciaenops.
What is the meaning of reticulate venation and parallel venation?
Definition. Reticulate venation refers to the presence of interconnected veins, which form a web-like network whereas parallel venation refers to the presence of parallelly- running secondary veins to a central, perpendicular primary vein.
Are flowers symmetrical?
A flower is considered symmetrical when each whorl consists of an equal number of parts or when the parts of any one whorl are multiples of that preceding it. Thus, a symmetrical flower may have five sepals, five petals, five stamens, and five carpels, or the number of any of these parts may be a multiple of five.
