The logical answer to this question would be b
A. direct B. indirect C. direct D. indirect
Competition occurs by direct and indirect means. Organisms interact directly by fighting (aggression) for scarce resources. Two eagles fighting over the salmon carcass and two colonies of ant clashing over a wasp are samples of aggression (direct competition)
Indirect competition happens when there is a common or limited <span>supply of at least one resource (food, water, and territory). </span>Use of this resource lessens and later depletes the amount available to others, or they compete for space.<span> Gray foxes preying on penguins and squirrels relying on nuts for food are samples of indirect competition.</span>
Explanation:
1. Increased green house gases: In addition to the loss of habitat, the lack of trees also allows a greater amount of greenhouse gases to be released into the atmosphere. Healthy forests absorbs carbon dioxide from the atmosphere, acting as valuable carbon sinks. Deforested areas lose that ability and release more carbon.
2. Water in the atmosphere:
The trees also help control the level of water in the atmosphere by helping to regulate the water cycle . In deforested areas, there is less water in the air to be returned to the soil. This then causes dryer soil and the inability to grow crops.
3. Soil erosion and flooding:
Further effects of deforestation include soil erosion and coastal flooding. Trees help the land to retain water and topsoil, which provides the rich nutrients to sustain additional forest life.
The ileum contains villi that project into the lumen and increase the amount of surface area.
Villi are small finger-like structures that project into the lumen of the small intestine. Villi increase the surface area of the intestinal walls for easy and quick absorption of digested food with the addition of digestive secretions. Villi vary in length from about 0.5 to 1 mm. They are usually found in large numbers at the beginning of the small intestine and they reduce toward the end of the tract.
They require moisture is a common feature of all protists
<u>Explanation:</u>
Protists are categorized based on how they eat, how they move and how similar they are to the other eukaryotic kingdoms. Protists are single-celled almost. One can speculate regarding protists as all eukaryotic organisms that are not animals, neither plants not a fungus. They also may seek for food like an animal or photosynthesize like a plant.
Protists are organisms that need moisture to live. They mostly live in aquatic habitats, though they may also grow in moist tree trunks and soil, among other environments. Protists also go through periods of sexual or asexual reproduction, based on their species or seldom their environmental situations.
