Food webs separate organisms by trophic level, but food chains do not.
Food chains show energy flow in an ecosystem, and food webs do not.
Food chains are linear, while food webs are complex.
Answer:
Option D, Food chains are linear, while food webs are complex.
Explanation:
A food chain is a linear organization in which the producer lies at the first stage followed by consumer organisms lying at primary, secondary and tertiary stages of food chain.
While in a food web, there can be several interlinked food chains or there can be an organism within the food web which is part of several food chains at an instance. Hence, the linearity of organization cannot be retained in case of food web thereby making it more complex than the food chain.
Hence, option D is correct.
C. eliminate waste.
D. avoid predators.
3. How would having a prehensile tail help a tree-dwelling chameleon? A. Its tail would help it grasp branches.
B. Its tail would help it capture food.
C. Its tail would help it balance in the treetops.
D. Its tail would help it maintain homeostasis.
Answer:
2. A. capture prey, and D. avoid predators
3. A. Its tail would help it grasp branches.
Explanation:
All animals need at least food, oxygen, shelter, space to survive. These needs, which are common to all animals, are fundamental to their survival and successful reproduction. However, from the options given in the question, not all animals need to capture prey to survive, as not all animals are carnivores. Some are herbivores that feed on plants, and do not prey on other animals. Also, not all animals need to avoid predators. For example, lions are predators and carnivores, they do not need to avoid predators. The correct options are option A and option D.
A prehensile tail is a tail that is adapted for grasping or holding, and it is common among arboreal animals, i.e. animals that dwell on trees. Therefore, a prehensile tail would help a tree-dwelling chameleon to grasp branches. The correct option is "A. Its tail would help it grasp branches."
an interacting community of different species
a group of individuals of the same species
a large area dominated by specific kinds of organisms
The phrase best describes a biome is large area dominated by specific kinds of organisms. The correct option is A.
A biome refers to a large geographical area on Earth that is characterized by distinct climate, vegetation, and animal life. It is defined by the dominant plant and animal species adapted to that particular environment. Each biome represents a unique ecosystem with specific abiotic (non-living) features, such as temperature, precipitation, soil type, and sunlight levels, which influence the types of organisms that can thrive in that region.
Thus, a biome can be described as a "large area dominated by specific kinds of organisms" due to the prevalence of certain species that have adapted to the environmental conditions prevalent in that biome.
