What is the number one cause of extinction?
Destruction of Habitat – It is currently the biggest cause of current extinctions. Deforestation has killed off more species than we can count.
What tree species grows best with full sunlight?
Oregon white oak (Quercus garryana) – The oak is a large deciduous tree and grows 25 to 70 feet tall and 30 to 60 feet wide. It is moderately hard to grow and flourishes best in full sun. It grows slowly, prefers well-drained soil, and sprouts acorns in the fall….Hours of Operations.

Why do small islands have higher extinction rates?
When an island is nearly empty, the extinction rate is necessarily low because few species are available to become extinct. And since the resources of an island are limited, as the number of resident species increases, the smaller and more prone to extinction their individual populations are likely to become.
How would you explain the difference between the two island as you have seen in your prediction?
Answer: The differences of each island is the soil type, the shape, the climate and the surrounded water. Most of the islands are small and contain volcanoes. Islands are inhabited by different plants and animals.
Which island fragment will support the lowest number of species?
SM far islands
Which habitat has the highest number of species?
forests
Do wolves live in the forest?
Wolves can thrive in a diversity of habitats from the tundra to woodlands, forests, grasslands and deserts. Wolves are carnivores—they prefer to eat large hoofed mammals such as deer, elk, bison, and moose. They also hunt smaller mammals such as beavers, rodents, and hares.
Where is the most biodiversity found on Earth?
Brazil
Which class has the largest number of animals?
In terms of numbers of species, insects certainly represent the largest percentage of the world’s organisms. There are more than 1 million species of insects that have been documented and studied by scientists.
Which class has the largest number of animals * 1 point?
Insecta
Which kingdom has the largest number of animals?
animal kingdom
Which phylum has a true Coelom?
arthropoda
What are the 3 types of Coelom?
There are three structural types of body plans related to the coelom.
- Acoelomates (animals with no coelom)
- Pseudocoelomates (animals with false coelom)
- Eucoelomates (animals with true coelom)
What does not have a true Coelom?
acoelomates
Do echinoderms have a true Coelom?
The six thousand species of marine animals in the phylum Echinodermata (“spiny-skinned”) are, like annelids, arthropods, chordates, and mollusks, characterized by a true coelom, or body cavity. However, echinoderms differ from all other coelomates (except for chordates) in their embryonic development.
Do earthworms have a true Coelom?
These animals belong to the phylum Annelida. Members of this phylum may be most familiar: the common earthworm, leech and nightcrawler belong to this group. Annelids have a true coelom, a condition called coelomate. That is the body cavity is lined on the inside and outside by mesoderm derived tissue.
Is a sand dollar an echinoderm?
Sand dollar, any of the invertebrate marine animals of the order Clypeastroida (class Echinoidea, phylum Echinodermata) that has a flat, disk-shaped body. They are close relatives of sea urchins and heart urchins. The sand dollar is particularly well adapted for burrowing in sandy substrates.
What do echinoderms have instead of a brain?
Instead of a brain, echinoderms have a ring of nerves located around their mouth area that governs their nervous responses. This ring coordinates their motion, their eating, basically anything that requires nerve control.
What liquid flows through echinoderms body to allow them to move?
The ring canal connects the radial canals (there are five in a pentaradial animal), and the radial canals move water into the ampullae, which have tube feet through which the water moves. By moving water through the unique water vascular system, the echinoderm can move and force open mollusk shells during feeding.
Where do most echinoderms live?
Most echinoderms, however, are found in reefs just lying beneath the surface of the water. No echinoderms are found in freshwater habitats or on land. This makes Echinodermata the largest animal phylum to only have ocean-based species.
Why do the tube feet of a sea cucumber shovel sand into its mouth?
Why do its tube feet shovel sand into the sea cucumber’s mouth? That is how it collects food. How are brittle stars patient predators? They catch prey by waving arms and grab plankton in feathers when it floats by.
Do echinoderms have brains?
Echinoderms have radial symmetry, many having five or multiples of five arms. They have a shell, made mainly of calcium carbonate, which is covered by skin. Echinoderms do not have brains, they have nerves running from the mouth into each arm or along the body.
What are the advantages and disadvantages to eating with an extendible stomach?
Advantages: As it moves it can keep eating. It moves out of the body to digest prey. It can release toxins to digest its prey easier. Disadvantages: While the stomach is out of the body the sea star is very vulnerable.
Why are echinoderms animals even though they have no brain?
Why are echinoderms animals even though they have no brain? – They are animals because they are movers and shakers in their domain. Do echinoderms have heads or faces? – They have no heads or faces 3. How many parts in the symmetry of sea stars? – There are 5 parts 4.
