Answer:
1. Minimum viable population is the estimate of the fewest number of organisms a population needs to avoid extinction.
2. The measurement will most likely stay the same if the number of offspring each female in the population produces increases.
3. If the death rate increases, this measurement will most likely increase.
Explanation:
Minimum Viable Population:
- Minimum viable population is an ecological threshold that signifies the minimum number of individuals required to prevent the species from going extinct.
- MVP determines population conservation benchmarks.
- MVP also helps in keeping a population genetically diverse as a limited number of individuals present limited mating opportunities and therefore limited genetic diversity.
Answer:
The correct answer is a. carnivores.
Photosynthesis is the process by which plants make their food from carbon dioxide and water in the presence of sunlight and chlorophyll. Hence, they convert light energy into chemical energy (food or glucose).
This energy is first utilized in the cellular respiration and then the rest in transferred to the primary consumers i.e. herbivores which feed on green plants.
They use this energy in their metabolic processes. The rest is transferred to the secondary consumers i.e. carnivores which feed on the herbivores.
Hence, energy from the photosynthesis indirectly passes to the carnivores via herbivores.
Answer:
Angiosperms are vascular plants bearing the seeds in fruits or mature ovaries whilst gymnosperms are other types of the plant which bears the seeds directly on the sporophylls but without any cover.
Explanation:
Examples of gymnosperms include cypress,pine, redwood, spruce and ginkgo.
Examples of angiosperms include apple, banana,peach, cherry and orange.
Also, angiosperms are seeds producing flowering plants whose seeds are enclosed within an ovary.
Gymnosperms are also seeds producing non flowering plants whose seeds are unenclosed.
Hope it helps.
