d. Alfred Russel Wallace
Answer: D. A soil that is 10 percent sand, 80 percent clay, and 10 percent silt.
A soil is an aggregate of sediments that is obtained after weathering of rocks, and organic matter being added by the biological activities of the living beings like decomposition of dead and decaying organisms.
Clay is a type of soil that has fine grained particles, it has better minerals and water retention capacity than other soils like sand and silt. This makes the clay more fertile over other soils and will be suitable for gardening. Therefore, the soil composition having more amount of clay in the soil composition will be the best soil for gardening.
Hence, A soil that is 10 percent sand, 80 percent clay, and 10 percent silt is a correct option.
Answer:
structural adaptation
Answer:
Adaptational
Explanation:
It needs to adapt to the different variety of food and drinks.
Food chains is a path that energy flows in an ecosystem and it usually indicate the level of eating within an ecosystem.
Producers are organism that usually absorb the sun’s energy and thereby convert the energy into food for growth and to make fruits or flowers. Examples include plants, algea
Primary Consumers: they are organism that only eat plants and can also be refers to as herbivores. However, example of herbivores includes grasshopper and bees.
Secondary consumers: they are organisms that eat both producers and primary consumers. They can be refers to as omnivores. Example includes beetle and wasp.
Level of Food chain
Plant---------Grasshopper---------Beetle
A food chain consisting of a producer, primary consumer, and secondary consumer includes grass as the producer, rabbits as the primary consumer, and foxes as the secondary consumer.
An example of a food chain that consists only of a producer, primary consumer, and secondary consumer is as follows:
In this example, the grass is the producer as it produces its own food through photosynthesis. The rabbit is the primary consumer as it feeds on the grass. The fox is the secondary consumer as it preys on the rabbit.
